GENERAL DESCRIPTION
The ADSP-21371/ADSP-21375 SHARC ? processors are mem-
bers of the SIMD SHARC family of DSPs that feature Analog

Devices’ Super Harvard Architecture. The processors are source
code compatible with the ADSP-2126x, ADSP-2136x, 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-

As shown in the functional block diagram on Page 1 , the pro-
cessors 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 processors achieve an instruction
cycle time of 3.75 ns at 266 MHz. With its SIMD computational
hardware, the processors can perform 1.596 GFLOPS running
at 266 MHz.

The diagram on Page 1 shows the two clock domains that make
up the ADSP-2137x processors. The core clock domain contains
the following 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
? One periodic interval timer with pinout
? On-chip SRAM (1M bit, ADSP-21371; 0.5M bit,
ADSP-21375)
? On-chip mask-programmable ROM (4M bit, ADSP-21371;
2M bit, ADSP-21375)
? JTAG test access port for emulation and boundary scan.
The JTAG provides software debug through user break-
points which allow flexible exception handling.
The diagram on Page 1 also shows the peripheral clock domains
(also known as the I/O processor) and contains the following
features:

Assumes two files in multichannel SIMD mode
? IOD0 (peripheral DMA) and IOD1 (external port DMA)
buses for 32-bit data transfers
