ADSP-21371/ADSP-21375

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-

sors optimized for high performance automotive audio

applications with their large on-chip SRAM and mask-pro-

grammable ROM, multiple internal buses to eliminate I/O

bottlenecks, and an innovative digital applications interface

(DAI).

Package

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

Table 1 shows performance benchmarks for these devices.

Table 2 shows the features of the individual product offerings.

• PM and DM buses capable of supporting four 32-bit data

transfers between memory and the core at every core pro-

cessor cycle

Table 1. Processor Benchmarks (at 266 MHz)

• One periodic interval timer with pinout

Speed

• On-chip SRAM (1M bit, ADSP-21371; 0.5M bit,

ADSP-21375)

Benchmark Algorithm

(at 266 MHz)

1024 Point Complex FFT (Radix 4, With Reversal) 34.5 s

• On-chip mask-programmable ROM (4M bit, ADSP-21371;

2M bit, ADSP-21375)

FIR Filter (per Tap)¹

IIR Filter (per Biquad)¹

1.88 ns

7.5 ns

• JTAG test access port for emulation and boundary scan.

The JTAG provides software debug through user break-

points which allow flexible exception handling.

Matrix Multiply (Pipelined)

[3 × 3] × [3 × 1]

[4 × 4] × [4 × 1]

16.91 ns

30.07 ns

The diagram on Page 1 also shows the peripheral clock domains

(also known as the I/O processor) and contains the following

features:

Divide (y/x)

13.1 ns

20.4 ns

Inverse Square Root

¹Assumes two files in multichannel SIMD mode

• IOD0 (peripheral DMA) and IOD1 (external port DMA)

buses for 32-bit data transfers

Table 2. ADSP-21371/ADSP-21375 Features

• Peripheral and external port bus for core connection

• Digital applications interface that includes four precision

clock generators (PCG), an S/PDIF-compatible digital

audio receiver/transmitter, an input data port (IDP), eight

serial ports, eight serial interfaces, a 20-bit parallel input

port (PDAP), and a flexible signal routing unit (DAI SRU).
