400 MHz High Performance Blackfin Processor

The ADSP-BF531 / ADSP-BF532 / ADSP-BF533 processors are members of the Blackfin® family of products, incorporating the Analog Devices, Inc./Intel Micro Signal Architecture (MSA). Blackfin 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.

The ADSP-BF531 / ADSP-BF532 / ADSP-BF533 processors are completely code and pin-compatible, differing only with respect to their performance and on-chip memory. Specific performance and memory configurations are shown in Table 1.
