GENERAL DESCRIPTION

The ADSP-BF531/ADSP-BF532/ADSP-BF533 processors are members of the Blackfin family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Black fin processors combine a dual-MAC state-of-the-art signal processing engine, the advantages of a clean, orthogonal RISC like microprocessor instruction set, and single instruction, multiple data (SIMD) multimedia capabilities into a single instruction set architecture.

FEATURES

Up to 600 MHz high performance Blackfin processor

Two 16-bit MACs, two 40-bit ALUs, four 8-bit video ALUs, 40-bit shifter

RISC-like register and instruction model for ease of programming and compiler-friendly support

Advanced debug, trace, and performance monitoring

0.85 V to 1.30 V core VDD with on-chip voltage regulation
