●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
●1.8 V, 2.5 V, and 3.3 V compliant I/O
●160-ball CSP_BGA, 169-ball PBGA, and 176-lead LQFP packages
