GENERAL DESCRIPTION
The ADSP-BF522/524/526 and ADSP-BF523/525/527 processors are members of the Blackfin family of products, incorporating the Analog Devices/Intel Micro Signal Architecture (MSA). Blackfin processors combine a dual-MAC state-ofthe-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,
