ADSP-BF531SBST400

Blackfin㈢嵌入式处理器 Blackfin㈢ Embedded Processor

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.
