GENERAL DESCRIPTION
The ADSP-21367/ADSP-21368/ADSP-21369 SHARC
proces-
sors are members of the SIMD SHARC family of DSPs that
feature Analog Devices’ Super Harvard Architecture. These pro-
cessors are source code-compatible with the ADSP-2126x and
ADSP-2116x DSPs as well as with first generation ADSP-2106x
SHARC processors in SISD (single-instruction, single-data)
mode. The processors are 32-bit/40-bit floating-point proces-
sors optimized for high performance automotive audio
applications with its large on-chip SRAM, mask programmable
ROM, multiple internal buses to eliminate I/O bottlenecks, and
an innovative digital applications interface (DAI).
As shown in the functional block diagram on Page 1, the
processors use two computational units to deliver a significant
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/ADSP-21368/
ADSP-21369 processors achieve an instruction cycle time of up
to 2.5 ns at 400 MHz. With its SIMD computational hardware,
the processors can perform 2.4 GFLOPS running at 400 MHz.
Table 1 shows performance benchmarks for these devices.
The diagram on Page 1 shows the two clock domains that make
up the ADSP-21367/ADSP-21368/ADSP-21369 processors. The
core clock domain contains the following features.
Two processing elements (PEx, PEy), each of which com-
prises 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 2x64-bit data
transfers between memory and the core at every core pro-
cessor cycle
One periodic interval timer with pinout
On-chip SRAM (2M bit)
On-chip mask-programmable ROM (6M bit)
JTAG test access port for emulation and boundary scan.
The JTAG provides software debug through user break-
points which allows flexible exception handling.
