PRELIMINARY TECHNICAL DATA

High Performance Floating-Point Processor

ADSP-21262

DAI incorporates a precision clock generator (PCG), and

Input Data Port (IDP) which includes the parallel data

acquisition port (PDAP), all under software control

through the Signal Routing Unit (SRU)

Preliminary Technical Data

SUMMARY

High performance 32-bit floating-point processor

optimized for high precision signal processing

applications

Single-Instruction Multiple-Data (SIMD) computational

architecture—two 32-bit IEEE floating-point/32-bit

fixed point/40-bit extended precision floating point

computational units, each with a multiplier, ALU,

shifter, and register file

On-chip memory — 2 Mbits of on-chip SRAM and a

dedicated 4 Mbits of on-chip mask-programmable

ROM

Six independent synchronous serial ports provide a

variety of serial communication protocols

The ADSP-21262 is available with a 200MHz core

instruction rate. For complete ordering information,

see Ordering Guide on page 43

High bandwidth I/O — A Parallel port, SPI port, Serial

ports, Digital Applications Interface (DAI), and JTAG.
