GENERAL DESCRIPTION

The ADSP-BF52x 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 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

Accepts a wide range of supply voltages for internal and I/O

operations. See Specifications on Page 28

Programmable on-chip voltage regulator (ADSP-BF523/

ADSP-BF525/ADSP-BF527 processors only)
