Intended Audience
The dspstak 21262sx is intended for DSP systems integrators, designers and programmers who may
wish to integrate a dspstak into their products. This manual is primarily aimed at users who have a
working knowledge of microcomputer technology and DSP related design. We assume that you are
familiar with the Analog Devices ADSP-21262 SHARC DSP.
Introduction
The dspstak™ 21262sx is a high performance digital signal processing engine based on the Analog
Devices ADSP-21262 SHARC
DSP. The ADSP-21262 supports 32 bit fixed point and 32/40 bit
floating point formats with SIMD instructions running at up to 200 MHz. This translates to a peak
computation rate of 1.2 GFLOPS. The ADSP-21262 also includes very flexible peripherals including
six independent serial ports (SPORTs) and a SPI port. The dspstak 21262sx Interconnect Port
supports the complete DAI interface, SPI, general I/O, clocks and power connections.
The dspstak 21262sx also includes USB and RS-232 ports for easy interfacing to the outside world.
It also has a JTAG interface to facilitate program development.
