ADSP-21367 Preliminary Technical Data
GENERAL DESCRIPTION
The ADSP-21367 SHARC processor is a members of the SIMD
SHARC family of DSPs that feature Analog Devices' Super Har-
vard Architecture. The ADSP-21367 is source code compatible
with the ADSP-2126x, and ADSP-2116x, DSPs as well as with
first generation ADSP-2106x SHARC processors in SISD (Sin-
gle-Instruction, Single-Data) mode. The ADSP-21367 is a 32-
bit/40-bit floating point processors optimized for high perfor-
mance automotive audio applications with its large on-chip
SRAM and mask-programmable ROM, multiple internal buses
to eliminate I/O bottlenecks, and an innovative Digital Audio
Interface (DAI).
As shown in the functional block diagram on Page 1, the
ADSP-21367 uses two computational units to deliver a signifi-
cant performance increase over the previous SHARC processors
on a range of DSP algorithms. Fabricated in a state-of-the-art,
high speed, CMOS process, the ADSP-21367 processor achieves
an instruction cycle time of 2.5 ns at 400 MHz. With its SIMD
computational hardware, the ADSP-21367 can perform 2.4
GFLOPS running at 400 MHz.
Table 1 shows performance benchmarks for the ADSP-21367.
The ADSP-21367 continues SHARC’s industry leading stan-
dards of integration for DSPs, combining a high performance
32-bit DSP core with integrated, on-chip system features.
The block diagram of the ADSP-21367 on Page 1, illustrates the
following architectural features:
Two processing elements, each of which comprises an
ALU, Multiplier, Shifter and Data Register File
Data Address Generators (DAG1, DAG2)
Program sequencer with instruction cache
PM and DM buses capable of supporting four 32-bit data
transfers between memory and the core at every core pro-
cessor cycle
Three Programmable Interval Timers with PWM Genera-
tion, PWM Capture/Pulse width Measurement, and
External Event Counter Capabilities
•On-Chip SRAM (2M bit)
On-Chip mask-programmable ROM (6M bit)
JTAG test access port
The block diagram of the ADSP-21367 on Page 1 also illustrates
the following architectural features:
DMA controller
Eight full duplex serial ports
Digital audio interface that includes four precision clock
generators (PCG), an input data port (IDP), an S/PDIF
receiver/transmitter, eight channels asynchronous sample
rate converters, eight serial ports, eight serial interfaces, a
16-bit parallel input port (PDAP), a flexible signal routing
unit (DAI SRU).
Digital peripheral interface that includes three timers, an
I
2
C interface, two UARTs, two serial peripheral interfaces
(SPI), and a flexible signal routing unit (DPI SRU).
ADSP-21367 FAMILY CORE ARCHITECTURE
The ADSP-21367 is code compatible at the assembly level with
the ADSP-2126x, ADSP-21160 and ADSP-21161, and with the
first generation ADSP-2106x SHARC processors. The ADSP-
21367 shares architectural features with the ADSP-2126x and
ADSP-2116x SIMD SHARC processors, as detailed in the fol-
lowing sections.
SIMD Computational Engine
The ADSP-21367 contains two computational processing ele-
ments that operate as a Single-Instruction Multiple-Data
(SIMD) engine. The processing elements are referred to as PEX
and PEY and each contains an ALU, multiplier, shifter and reg-
ister file. PEX is always active, and PEY may be enabled by
setting the PEYEN mode bit in the MODE1 register. When this
mode is enabled, the same instruction is executed in both pro-
cessing elements, but each processing element operates on
different data. This architecture is efficient at executing math
intensive DSP algorithms.
Entering SIMD mode also has an effect on the way data is trans-
ferred between memory and the processing elements. When in
SIMD mode, twice the data bandwidth is required to sustain
computational operation in the processing elements. Because of
this requirement, entering SIMD mode also doubles the band-
width between memory and the processing elements. When
using the DAGs to transfer data in SIMD mode, two data values
are transferred with each access of memory or the register file.
Independent, Parallel Computation Units
Within each processing element is a set of computational units.
The computational units consist of an arithmetic/logic unit
(ALU), multiplier, and shifter. These units perform all opera-
tions in a single cycle. The three units within each processing
element are arranged in parallel, maximizing computational
throughput. Single multifunction instructions execute parallel
ALU and multiplier operations. In SIMD mode, the parallel
ALU and multiplier operations occur in both processing ele-

ments. These computation units support IEEE 32-bit single-
precision floating-point, 40-bit extended precision floating-
point, and 32-bit fixed-point data formats.
Data Register File
A general-purpose data register file is contained in each pro-
cessing element. The register files transfer data between the
computation units and the data buses, and store intermediate
results. These 10-port, 32-register (16 primary, 16 secondary)
register files, combined with the ADSP-2136x enhanced Har-
vard architecture, allow unconstrained data flow between
computation units and internal memory. The registers in PEX
are referred to as R0-R15 and in PEY as S0-S15.
Single-Cycle Fetch of Instruction and Four Operands
The ADSP-21367 features an enhanced Harvard architecture in
which the data memory (DM) bus transfers data and the pro-
gram memory (PM) bus transfers both instructions and data
(see Figure 1 on page 1). With the ADSP-21367’s separate pro-
gram and data memory buses and on-chip instruction cache,
the processor can simultaneously fetch four operands (two over
each data bus) and one instruction (from the cache), all in a sin-
gle cycle.
Instruction Cache
The ADSP-21367 includes an on-chip instruction cache that
enables three-bus operation for fetching an instruction and four
data values. The cache is selective—only the instructions whose
fetches conflict with PM bus data accesses are cached. This
cache allows full-speed execution of core, looped operations
such as digital filter multiply-accumulates, and FFT butterfly
processing.
Data Address Generators With Zero-Overhead Hardware
Circular Buffer Support
The ADSP-21367’s two data address generators (DAGs) are
used for indirect addressing and implementing circular data
buffers in hardware. Circular buffers allow efficient program-
ming of delay lines and other data structures required in digital
signal processing, and are commonly used in digital filters and
Fourier transforms. The two DAGs of the ADSP-21367 contain
sufficient registers to allow the creation of up to 32 circular buff-
ers (16 primary register sets, 16 secondary). The DAGs
automatically handle address pointer wraparound, reduce over-
head, increase performance, and simplify implementation.
Circular buffers can start and end at any memory location.
Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations, for concise programming. For example, the
ADSP-21367 can conditionally execute a multiply, an add, and a
subtract in both processing elements while branching and fetch-
ing up to four 32-bit values from memory—all in a single
instruction.
ADSP-21367 MEMORY
The ADSP-21367 adds the following architectural features to
the SIMD SHARC family core.
On-Chip Memory
The ADSP-21367 contains two megabits of internal RAM and
six megabits of internal mask-programmable ROM. Each block
can be configured for different combinations of code and data
storage (see Table 2 on page 6). Each memory block supports
single-cycle, independent accesses by the core processor and I/O
processor. The ADSP-21367 memory architecture, in combina-
tion with its separate on-chip buses, allow two data transfers
from the core and one from the I/O processor, in a single cycle.
The ADSP-21367’s, SRAM can be configured as a maximum of
64K words of 32-bit data, 128K words of 16-bit data, 42K words
of 48-bit instructions (or 40-bit data), or combinations of differ-
ent word sizes up to two megabits. All of the memory can be
accessed as 16-bit, 32-bit, 48-bit, or 64-bit words. A 16-bit float-
ing-point storage format is supported that effectively doubles
the amount of data that may be stored on-chip. Conversion
between the 32-bit floating-point and 16-bit floating-point for-
mats is performed in a single instruction. While each memory
block can store combinations of code and data, accesses are
most efficient when one block stores data using the DM bus for
transfers, and the other block stores instructions and data using
the PM bus for transfers.
Using the DM bus and PM buses, with one bus dedicated to
each memory block, assures single-cycle execution with two
data transfers. In this case, the instruction must be available in
the cache.
EXTERNAL MEMORY
The External Port on the ADSP-21367 SHARC provides a high
performance, glueless interface to a wide variety of industry-
standard memory devices. The 32-bit wide bus may be used to
interface to synchronous and/or asynchronous memory devices
through the use of it's separate internal memory controllers: the
first is an SDRAM controller for connection of industry-stan-
dard synchronous DRAM devices and DIMMs (Dual Inline
Memory Module), while the second is an asynchronous mem-
ory controller intended to interface to a variety of memory
devices. Four memory select pins enable up to four separate
devices to coexist, supporting any desired combination of syn-
chronous and asynchronous device types. Non SDRAM
external memory address space is shown in Table 3.
SDRAM Controller
The SDRAM controller provides an interface to up to four sepa-
rate banks of industry-standard SDRAM devices or DIMMs, at
speeds up to f
SCLK
. Fully compliant with the SDRAM standard,
each bank can has it's own memory select line (MS0–MS3), and
can be configured to contain between 16M bytes and
128M bytes of memory. SDRAM external memory address
space is shown in Table 4.
The controller maintains all of the banks as a contiguous
address space so that the processor sees this as a single address
space, even if different size devices are used in the different
banks.
Rev. PrC | Page 6 of 52 | June 2005
ADSP-21367 Preliminary Technical Data
A set of programmable timing parameters is available to config-
ure the SDRAM banks to support slower memory devices. The
memory banks can be configured as either 32 bits wide for max-
imum performance and bandwidth or 16 bits wide for
minimum device count and lower system cost.
The SDRAM controller address, data, clock, and command pins
can drive loads up to 30 pF. For larger memory systems, the
SDRAM controller external buffer timing should be selected
and external buffering should be provided so that the load on
the SDRAM controller pins does not exceed 30 pF.
Asynchronous Controller
The asynchronous memory controller provides a configurable
interface for up to four separate banks of memory or I/O
devices. Each bank can be independently programmed with dif-
ferent timing parameters, enabling connection to a wide variety
of memory devices including SRAM, ROM, flash, and EPROM,
as well as I/O devices that interface with standard memory con-
trol lines. Bank0 occupies a 14.7M word window and banks 1, 2,
and 3 occupy a 16M word window in the processor’s address
space but, if not fully populated, these windows are not made
contiguous by the memory controller logic. The banks can also
be configured as 8-bit, 16-bit, or 32-bit wide buses for ease of
interfacing to a range of memories and I/O devices tailored
either to high performance or to low cost and power.
The asynchronous memory controller is capable of a maximum
throughput of 267M bytes/sec using a 66MHz external bus
speed. Other features include 8 to 32-bit and 16 to 32-bit pack-
ing and unpacking, booting from Bank Select 1, and support for
delay line DMA.

•Two universal asynchronous receiver/transmitters
(UARTs)

C
DMA Controller
The ADSP-21367’s on-chip DMA controller allows data trans-
fers without processor intervention. The DMA controller
operates independently and invisibly to the processor core,
allowing DMA operations to occur while the core is simulta-
neously executing its program instructions. DMA transfers can
occur between the ADSP-21367’s internal memory and its serial
ports, the SPI-compatible (Serial Peripheral Interface) ports, the
IDP (Input Data Port), the Parallel Data Acquisition Port
(PDAP) or the UART. Thirty-four channels of DMA are avail-
able on the ADSP-21367—sixteen via the serial ports, eight via
the Input Data Port, four for the UARTs, two for the SPI inter-
face, two for the external port, and two for memory-to-memory
transfers. Programs can be downloaded to the ADSP-21367
using DMA transfers. Other DMA features include interrupt
generation upon completion of DMA transfers, and DMA
chaining for automatic linked DMA transfers.
Delay Line DMA
The ADSP-21367 processor provides Delay Line DMA func-
tionality. This allows processor reads and writes to external
Delay Line Buffers (and hence to external memory) with limited
core interaction.
Digital Audio Interface (DAI)
The Digital Audio Interface (DAI) provides the ability to con-
nect various peripherals to any of the DSPs DAI pins
(DAI_P20–1).
Programs make these connections using the Signal Routing
Unit (SRU, shown in Figure 1.
The SRU is a matrix routing unit (or group of multiplexers) that
enables the peripherals provided by the DAI to be intercon-
nected under software control. This allows easy use of the DAI
associated peripherals for a much wider variety of applications
by using a larger set of algorithms than is possible with non con-
figurable signal paths.
The DAI also includes eight serial ports, an S/PDIF
receiver/transmitter, four precision clock generators (PCG),
eight channels of synchronous sample rate converters, and an
input data port (IDP). The IDP provides an additional input
path to the ADSP-21367 core, configurable as either eight chan-
nels of I
2
S serial data or as seven channels plus a single 20-bit
wide synchronous parallel data acquisition port. Each data
channel has its own DMA channel that is independent from the
ADSP-21367's serial ports.
For complete information on using the DAI, see the ADSP-
2136x SHARC Processor Hardware Reference for the ADSP-
21367/8/9 Processors.
Serial Ports
The ADSP-21367 features eight synchronous serial ports that
provide an inexpensive interface to a wide variety of digital and
mixed-signal peripheral devices such as Analog devices AD183x
family of audio codecs, ADCs, and DACs. The serial ports are
made up of two data lines, a clock and frame sync. The data
lines can be programmed to either transmit or receive and each
data line has a dedicated DMA channel.
Serial ports are enabled via 16 programmable and simultaneous
receive or transmit pins that support up to 32 transmit or 32
receive channels of audio data when all eight SPORTS are
enabled, or eight full duplex TDM streams of 128 channels per
frame.
The serial ports operate at a maximum data rate of 50M bits/s.
Serial port data can be automatically transferred to and from
on-chip memory via dedicated DMA channels. Each of the
serial ports can work in conjunction with another serial port to
provide TDM support. One SPORT provides two transmit sig-
nals while the other SPORT provides the two receive signals.
The frame sync and clock are shared.
Serial ports operate in five modes:
Standard DSP serial mode
•Multichannel (TDM) mode with support for Packed I
2
S
mode
•I
2
S mode
•Packed I
2
S mode
Left-justified sample pair mode
Left-justified sample pair mode is a mode where in each frame
sync cycle two samples of data are transmitted/received—one
sample on the high segment of the frame sync, the other on the
low segment of the frame sync. Programs have control over var-
ious attributes of this mode.
Each of the serial ports supports the left-justified sample pair
and I
2
S protocols (I
2
S is an industry standard interface com-
monly used by audio codecs, ADCs and DACs such as the
Analog Devices AD183x family), with two data pins, allowing
four left-justified sample pair or I
2
S channels (using two stereo
devices) per serial port, with a maximum of up to 32 I
2
S chan-
nels. The serial ports permit little-endian or big-endian
transmission formats and word lengths selectable from 3 bits to
32 bits. For the left-justified sample pair and I
2
S modes, data-

ADSP-21367 Preliminary Technical Data
word lengths are selectable between 8 bits and 32 bits. Serial
ports offer selectable synchronization and transmit modes as
well as optional µ-law or A-law companding selection on a per
channel basis. Serial port clocks and frame syncs can be inter-
nally or externally generated.
The serial ports also contain frame sync error detection logic
where the serial ports detect frame syncs that arrive early (for
example frame syncs that arrive while the transmission/recep-
tion of the previous word is occurring). All the serial ports also
share one dedicated error interrupt.
S/PDIF Compatible Digital Audio Receiver/Transmitter
and Synchronous/Asynchronous Sample Rate Converter
The S/PDIF receiver/transmitter has no separate DMA chan-
nels. It receives audio data in serial format and converts it into a
biphase encoded signal. The serial data input to the
receiver/transmitter can be formatted as left justified, I
2
S or
right justified with word widths of 16, 18, 20, or 24 bits.
The serial data, clock, and frame sync inputs to the S/PDIF
receiver/transmitter are routed through the Signal Routing Unit
(SRU). They can come from a variety of sources such as the
SPORTs, external pins, the precision clock generators (PCGs),
or the sample rate converters (SRC) and are controlled by the
SRU control registers.
The sample rate converter (SRC) contains four SRC blocks and
is the same core as that used in the AD1896 192 kHz Stereo
Asynchronous Sample Rate Converter and provides up to
128dB SNR. The SRC block is used to perform synchronous or
asynchronous sample rate conversion across independent stereo
channels, without using internal processor resources. The four
SRC blocks can also be configured to operate together to con-
vert multichannel audio data without phase mismatches.
Finally, the SRC is used to clean up audio data from jittery clock
sources such as the S/PDIF receiver.
Digital Peripheral Interface (DPI)
The Digital Peripheral Interface provides connections to two
serial peripheral interface ports (SPI), two universal asynchro-
nous receiver-transmitters (UARTs), a Two Wire Interface
(TWI), 12 Flags, and three general-purpose timers.
Serial Peripheral (Compatible) Interface
The ADSP-21367 SHARC processor contains two Serial Periph-
eral Interface ports (SPIs). The SPI is an industry standard
synchronous serial link, enabling the ADSP-21367 SPI compati-
ble port to communicate with other SPI compatible devices. The
SPI consists of two data pins, one device select pin, and one
clock pin. It is a full-duplex synchronous serial interface, sup-
porting both master and slave modes. The SPI port can operate
in a multimaster environment by interfacing with up to four
other SPI compatible devices, either acting as a master or slave
device. The ADSP-21367 SPI compatible peripheral implemen-
tation also features programmable baud rate and clock phase
and polarities. The ADSP-21367 SPI compatible port uses open
drain drivers to support a multimaster configuration and to
avoid data contention.
UART Port
The ADSP-21367 processor provides a full-duplex Universal
Asynchronous Receiver/Transmitter (UART) port, which is
fully compatible with PC-standard UARTs. The UART port
provides a simplified UART interface to other peripherals or
hosts, supporting full-duplex, DMA-supported, asynchronous
transfers of serial data. The UART also has multiprocessor com-
munication capability using 9-bit address detection. This allows
it to be used in multidrop networks through the RS-485 data
interface standard. The UART port also includes support for 5
to 8 data bits, 1 or 2 stop bits, and none, even, or odd parity. The
UART port supports two modes of operation:
PIO (Programmed I/O) – The processor sends or receives
data by writing or reading I/O-mapped UART registers.
The data is double-buffered on both transmit and receive.
DMA (Direct Memory Access) – The DMA controller
transfers both transmit and receive data. This reduces the
number and frequency of interrupts required to transfer
data to and from memory. The UART has two dedicated
DMA channels, one for transmit and one for receive. These
DMA channels have lower default priority than most DMA
channels because of their relatively low service rates.
The UART port's baud rate, serial data format, error code gen-
eration and status, and interrupts are programmable:
Supporting bit rates ranging from (f
SCLK
/ 1,048,576) to
(f
SCLK
/16) bits per second.
Supporting data formats from 7 to12 bits per frame.
Both transmit and receive operations can be configured to
generate maskable interrupts to the processor.
Where the 16-bit UART_Divisor comes from the DLH register
(most significant 8 bits) and DLL register (least significant
8bits).
In conjunction with the general-purpose timer functions, auto-
baud detection is supported.
Timers
The ADSP-21367 has a total of four timers: a core timer that can
generate periodic software interrupts and three general purpose
timers that can generate periodic interrupts and be indepen-
dently set to operate in one of three modes:
Pulse Waveform Generation mode
Pulse Width Count /Capture mode
External Event Watchdog mode
The core timer can be configured to use FLAG3 as a Timer
Expired signal, and each general purpose timer has one bidirec-
tional pin and four registers that implement its mode of
operation: a 6-bit configuration register, a 32-bit count register,
a 32-bit period register, and a 32-bit pulse width register. A sin-
gle control and status register enables or disables all three
general purpose timers independently.

Two Wire Interface Port (TWI)
The TWI is a bi-directional 2-wire, serial bus used to move 8-bit
data while maintaining compliance with the I2C bus protocol.
The TWI Master incorporates the following features:
Simultaneous Master and Slave operation on multiple
device systems with support for multi master data
arbitration
Digital filtering and timed event processing
7 and 10 bit addressing
100K bits/s and 400K bits/s data rates
Low interrupt rate
Pulse Width Modulation
The PWM module is a flexible, programmable, PWM waveform
generator that can be programmed to generate the required
switching patterns for various applications related to motor and
engine control or audio power control. The PWM generator can
generate either center-aligned or edge-aligned PWM wave-
forms. In addition, it can generate complementary signals on
two outputs in paired mode or independent signals in non
paired mode (applicable to a single group of four PWM
waveforms).
The entire PWM module has four groups of four PWM outputs
each. Therefore, this module generates 16 PWM outputs in
total. Each PWM group produces two pairs of PWM signals on
the four PWM outputs.
The PWM generator is capable of operating in two distinct
modes while generating center-aligned PWM waveforms: single
update mode or double update mode. In single update mode the
duty cycle values are programmable only once per PWM period.
This results in PWM patterns that are symmetrical about the
mid-point of the PWM period. In double update mode, a sec-
ond updating of the PWM registers is implemented at the mid-
point of the PWM period. In this mode, it is possible to produce
asymmetrical PWM patterns that produce lower harmonic dis-
tortion in three-phase PWM inverters.
ROM Based Security
The ADSP-21367 has a ROM security feature that provides
hardware support for securing user software code by preventing
unauthorized reading from the internal code when enabled.
When using this feature, the processor does not boot-load any
external code, executing exclusively from internal SRAM/ROM.
Additionally, the processor is not freely accessible via the JTAG
port. Instead, a unique 64-bit key, which must be scanned in
through the JTAG or Test Access Port will be assigned to each
customer. The device will ignore a wrong key. Emulation fea-
tures and external boot modes are only available after the
correct key is scanned.
SYSTEM DESIGN
The following sections provide an introduction to system design
options and power supply issues.
Program Booting
The internal memory of the ADSP-21367 boots at system
power-up from an 8-bit EPROM via the external port, an SPI
master, an SPI slave or an internal boot. Booting is determined
by the Boot Configuration (BOOTCFG1–0) pins (see Table 7 on
page 15). Selection of the boot source is controlled via the SPI as
either a master or slave device, or it can immediately begin exe-
cuting from ROM.
Power Supplies
The ADSP-21367 has separate power supply connections for the
internal (V
DDINT
), external (V
DDEXT
), and analog (A
VDD
/A
VSS
)
power supplies. The internal and analog supplies must meet the
1.3V requirement. The external supply must meet the 3.3V
requirement. All external supply pins must be connected to the
same power supply.
Note that the analog supply pin (A
VDD
) powers the ADSP-
21367’s internal clock generator PLL. To produce a stable clock,
it is recommended that PCB designs use an external filter circuit
for the A
VDD
pin. Place the filter components as close as possi-
ble to the A
VDD
/A
VSS
pins. For an example circuit, see Figure 2.
(A recommended ferrite chip is the muRata
BLM18AG102SN1D). To reduce noise coupling, the PCB
should use a parallel pair of power and ground planes for
V
DDINT
and GND. Use wide traces to connect the bypass capac-
itors to the analog power (A
VDD
) and ground (A
VSS
) pins. Note
that the A
VDD
and A
VSS
pins specified in Figure 2 are inputs to
the processor and not the analog ground plane on the board—
the A
VSS
pin should connect directly to digital ground (GND) at
the chip.
Target Board JTAG Emulator Connector
Analog Devices DSP Tools product line of JTAG emulators uses
the IEEE 1149.1 JTAG test access port of the ADSP-21367 pro-
cessor to monitor and control the target board processor during
emulation. Analog Devices DSP Tools product line of JTAG
emulators provides emulation at full processor speed, allowing
inspection and modification of memory, registers, and proces-
sor stacks. The processor's JTAG interface ensures that the
emulator will not affect target system loading or timing.

priate “Emulator Hardware User's Guide”.

ADSP-21367 Preliminary Technical Data
DEVELOPMENT TOOLS
The ADSP-21367 is supported with a complete set of
CROSSCORE
®
software and hardware development tools,
including Analog Devices emulators and VisualDSP++
®
devel-
opment environment. The same emulator hardware that
supports other SHARC processors also fully emulates the
ADSP-21367.
The VisualDSP++ project management environment lets pro-
grammers develop and debug an application. This environment
includes an easy to use assembler (which is based on an alge-
braic syntax), an archiver (librarian/library builder), a linker, a
loader, a cycle-accurate instruction-level simulator, a C/C++
compiler, and a C/C++ runtime library that includes DSP and
mathematical functions. A key point for these tools is C/C++
code efficiency. The compiler has been developed for efficient
translation of C/C++ code to DSP assembly. The SHARC has
architectural features that improve the efficiency of compiled
C/C++ code.
The VisualDSP++ debugger has a number of important fea-
tures. Data visualization is enhanced by a plotting package that
offers a significant level of flexibility. This graphical representa-
tion of user data enables the programmer to quickly determine
the performance of an algorithm. As algorithms grow in com-
plexity, this capability can have increasing significance on the
designer’s development schedule, increasing productivity. Sta-
tistical profiling enables the programmer to non intrusively poll
the processor as it is running the program. This feature, unique
to VisualDSP++, enables the software developer to passively
gather important code execution metrics without interrupting
the real-time characteristics of the program. Essentially, the
developer can identify bottlenecks in software quickly and effi-
ciently. By using the profiler, the programmer can focus on
those areas in the program that impact performance and take
corrective action.
Debugging both C/C++ and assembly programs with the
VisualDSP++ debugger, programmers can:
View mixed C/C++ and assembly code (interleaved source
and object information)
Insert breakpoints
Set conditional breakpoints on registers, memory,
and stacks
Trace instruction execution
Perform linear or statistical profiling of program execution
Fill, dump, and graphically plot the contents of memory
Perform source level debugging
Create custom debugger windows
The VisualDSP++ IDDE lets programmers define and manage
DSP software development. Its dialog boxes and property pages
let programmers configure and manage all of the SHARC devel-
opment tools, including the color syntax highlighting in the
VisualDSP++ editor. This capability permits programmers to:
Control how the development tools process inputs and
generate outputs
Maintain a one-to-one correspondence with the tool’s
command line switches
The VisualDSP++ Kernel (VDK) incorporates scheduling and
resource management tailored specifically to address the mem-
ory and timing constraints of DSP programming. These
capabilities enable engineers to develop code more effectively,
eliminating the need to start from the very beginning, when
developing new application code. The VDK features include
Threads, Critical and Unscheduled regions, Semaphores,
Events, and Device flags. The VDK also supports Priority-based,
Preemptive, Cooperative, and Time-Sliced scheduling
approaches. In addition, the VDK was designed to be scalable. If
the application does not use a specific feature, the support code
for that feature is excluded from the target system.
Because the VDK is a library, a developer can decide whether to
use it or not. The VDK is integrated into the VisualDSP++
development environment, but can also be used via standard
command line tools. When the VDK is used, the development
environment assists the developer with many error-prone tasks
and assists in managing system resources, automating the gen-
eration of various VDK based objects, and visualizing the
system state, when debugging an application that uses the VDK.
VisualDSP++ Component Software Engineering (VCSE) is
Analog Devices’ technology for creating, using, and reusing
software components (independent modules of substantial
functionality) to quickly and reliably assemble software applica-
tions. Download components from the Web and drop them into
the application. Publish component archives from within
VisualDSP++. VCSE supports component implementation in
C/C++ or assembly language.
Use the Expert Linker to visually manipulate the placement of
code and data on the embedded system. View memory utiliza-
tion in a color-coded graphical form, easily move code and data
to different areas of the processor or external memory with the
drag of the mouse, examine run time stack and heap usage. The
Expert Linker is fully compatible with the existing Linker Defi-
nition File (LDF), allowing the developer to move between the
graphical and textual environments.
In addition to the software and hardware development tools
available from Analog Devices, third parties provide a wide
range of tools supporting the SHARC processor family. Hard-
ware tools include SHARC processor PC plug-in cards. Third
party software tools include DSP libraries, real-time operating
systems, and block diagram design tools.

Designing an Emulator-Compatible DSP Board (Target)
The Analog Devices family of emulators are tools that every
DSP developer needs to test and debug hardware and software
systems. Analog Devices has supplied an IEEE 1149.1 JTAG
Test Access Port (TAP) on each JTAG DSP. Nonintrusive in-
circuit emulation is assured by the use of the processor’s JTAG
interface—the emulator does not affect target system loading or
timing. The emulator uses the TAP to access the internal fea-
tures of the processor, allowing the developer to load code, set
breakpoints, observe variables, observe memory, and examine
registers. The processor must be halted to send data and com-
mands, but once an operation has been completed by the
emulator, the DSP system is set running at full speed with no
impact on system timing.
To use these emulators, the target board must include a header
that connects the DSP’s JTAG port to the emulator.
For details on target board design issues including mechanical
layout, single processor connections, signal buffering, signal ter-
mination, and emulator pod logic, see the EE-68: Analog Devices
JTAG Emulation Technical Reference on the Analog Devices
website (www.analog.com)—use site search on “EE-68.” This
document is updated regularly to keep pace with improvements
to emulator support.
Evaluation Kit
Analog Devices offers a range of EZ-KIT Lite evaluation plat-
forms to use as a cost effective method to learn more about
developing or prototyping applications with Analog Devices
processors, platforms, and software tools. Each EZ-KIT Lite
includes an evaluation board along with an evaluation suite of
the VisualDSP++ development and debugging environment
with the C/C++ compiler, assembler, and linker. Also included
are sample application programs, power supply, and a USB
cable. All evaluation versions of the software tools are limited
for use only with the EZ-KIT Lite product.
The USB controller on the EZ-KIT Lite board connects the
board to the USB port of the user’s PC, enabling the
VisualDSP++ evaluation suite to emulate the on-board proces-
sor in-circuit. This permits the customer to download, execute,
and debug programs for the EZ-KIT Lite system. It also allows
in-circuit programming of the on-board Flash device to store
user-specific boot code, enabling the board to run as a standal-
one unit without being connected to the PC.
With a full version of VisualDSP++ installed (sold separately),
engineers can develop software for the EZ-KIT Lite or any cus-
tom defined system. Connecting one of Analog Devices JTAG
emulators to the EZ-KIT Lite board enables high-speed, non-
intrusive emulation.

source. Connecting the necessary components to CLKIN and XTAL enables the internal
clock generator. Connecting the external clock to CLKIN while leaving XTAL uncon-
nected configures the ADSP-21367 to use the external clock source such as an external
clock oscillator. CLKIN may not be halted, changed, or operated below the specified
frequency.

TIMING SPECIFICATIONS
The ADSP-21367’s internal clock (a multiple of CLKIN) pro-
vides the clock signal for timing internal memory, processor
core, and serial ports. During reset, program the ratio between
the processor’s internal clock frequency and external (CLKIN)
clock frequency with the CLKCFG1–0 pins (see Table 8 on
page 15). To determine switching frequencies for the serial
ports, divide down the internal clock, using the programmable
divider control of each port (DIVx for the serial ports).

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADSP-21367 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
Rev. PrC | Page 18 of 52 | June 2005
ADSP-21367 Preliminary Technical Data
Figure 3 shows Core to CLKIN ratios of 6:1, 16:1 and 32:1 with
external oscillator or crystal. Note that more ratios are possible
and can be set through software using the power management
control register (PMCTL). For more information, see the ADSP-
2136x SHARC Processor Programming Reference.
The ADSP-21367’s internal clock switches at higher frequencies
than the system input clock (CLKIN). To generate the internal
clock, the processor uses an internal phase-locked loop (PLL).
This PLL-based clocking minimizes the skew between the sys-
tem clock (CLKIN) signal and the processor’s internal clock.
Note the definitions of various clock periods shown in Table 10
which are a function of CLKIN and the appropriate ratio con-
trol shown in Table 9.
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results
for an individual device, the values given in this data sheet
reflect statistical variations and worst cases. Consequently, it is
not meaningful to add parameters to derive longer times. See
Figure 38 on page 45 under Test Conditions for voltage refer-
ence levels.
Switching Characteristics specify how the processor changes its
signals. Circuitry external to the processor must be designed for
compatibility with these signal characteristics. Switching char-
acteristics describe what the processor will do in a given
circumstance. Use switching characteristics to ensure that any
timing requirement of a device connected to the processor (such
as memory) is satisfied.
Timing Requirements apply to signals that are controlled by cir-
cuitry external to the processor, such as the data input for a read
operation. Timing requirements guarantee that the processor
operates correctly with other devices.

Clock Signals
The ADSP-21367 can use an external clock or a crystal. See the
CLKIN pin description in Table 5. The programmer can config-
ure the ADSP-21367 to use its internal clock generator by
connecting the necessary components to CLKIN and XTAL.
Figure 6 shows the component connections used for a crystal
operating in fundamental mode. Note that the clock rate is
achieved using a 16.67 MHz crystal and a PLL multiplier ratio
16:1 (CCLK:CLKIN achieves a clock speed of 400 MHz). To
achieve the full core clock rate, programs need to configure the
multiplier bits in the PMCTL register.

ADSP-21367 Preliminary Technical Data
Serial Ports
To determine whether communication is possible between two
devices at clock speed n, the following specifications must be
confirmed: 1) frame sync delay and frame sync setup and hold,
2) data delay and data setup and hold, and 3) SCLK width.
Serial port signals (SCLK, FS, data channel A, data channel B)
are routed to the DAI_P20–1 pins using the SRU. Therefore, the
timing specifications provided below are valid at the
DAI_P20–1 pins.

SPDIF Transmitter
Serial data input to the SPDIF transmitter can be formatted as
left justified, I
2
S or right justified with word widths of 16, 18, 20,
or 24 bits. The following sections provide timing for the
transmitter.
SPDIF TransmitterSerial Input Waveforms
Figure 26 shows the right-justified mode. LRCLK is HI for the
left channel and LO for the right channel. Data is valid on the
rising edge of SCLK. The MSB is delayed 12-bit clock periods
(in 20-bit output mode) or 16-bit clock periods (in 16-bit output
mode) from an LRCLK transition, so that when there are 64
SCLK periods per LRCLK period, the LSB of the data will be
right-justified to the next LRCLK transition.
Figure 27 shows the default I2S-justified mode. LRCLK is LO
for the left channel and HI for the right channel. Data is valid on
the rising edge of SCLK. The MSB is left-justified to an LRCLK
transition but with a single SCLK period delay.
Figure 28 shows the left-justified mode. LRCLK is HI for the left
channel and LO for the right channel. Data is valid on the rising
edge of SCLK. The MSB is left-justified to an LRCLK transition
with no MSB delay.

ADSP-21367 Preliminary Technical Data
Universal Asynchronous Receiver-Transmitter
(UART) Port—Receive and Transmit Timing
Figure 33 describes UART port receive and transmit operations.
The maximum baud rate is SCLK/16. As shown in Figure 33
there is some latency between the generation of internal UART
interrupts and the external data operations. These latencies are
negligible at the data transmission rates for the UART.

TWI Controller Timing
Table 40 and Figure 34 provide timing information for the TWI
interface. Input Signals (SCL, SDA) are routed to the
DPI_P14–1 pins using the SRU. Therefore, the timing specifica-
tions provided below are valid at the DPI_P14–1 pins.

OUTPUT DRIVE CURRENTS
Figure 36 shows typical I-V characteristics for the output driv-
ers of the ADSP-21367. The curves represent the current drive
capability of the output drivers as a function of output voltage.
TEST CONDITIONS
The ac signal specifications (timing parameters) appear
Table 13 on page 21 through Table 41 on page 44. These include
output disable time, output enable time, and capacitive loading.
The timing specifications for the SHARC apply for the voltage
reference levels in Figure 37.
Timing is measured on signals when they cross the 1.5 V level as
described in Figure 38. All delays (in nanoseconds) are mea-
sured between the point that the first signal reaches 1.5 V and
the point that the second signal reaches 1.5 V.
CAPACITIVE LOADING
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see Figure 37). Figure 41 shows graphically
how output delays and holds vary with load capacitance. The
graphs of Figure 39, Figure 40, and Figure 41 may not be linear
outside the ranges shown for Typical Output Delay vs. Load
Capacitance and Typical Output Rise Time (20%-80%, V=Min)
vs. Load Capacitance.
THERMAL CHARACTERISTICS
The ADSP-21367 processor is rated for performance over the
temperature range specified in Recommended Operating Con-
ditions on Page 16.
