GENERAL DESCRIPTION

The ADSP-BF534/ADSP-BF536/ADSP-BF537 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-of-the-art signal processing engine, the advantages of a clean, orthogonal RISClike microprocessor instruction set, and single-instruction, multiple-data (SIMD) multimedia capabilities into a single instruction-set architecture.

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

0.8 V to 1.2 V core VDD with on-chip voltage regulation

2.5 V and 3.3 V-tolerant I/O with specific 5 V-tolerant pins
