GENERAL DESCRIPTION

The ADSP-BF535 processor is a member of the Blackfin processor family of products, incorporating the Micro Signal Architecture (MSA), jointly developed by Analog Devices, Inc. and Intel Corporation. The architecture combines 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.
