ADSP-BF548MBBCZ-5M

嵌入式处理器 Embedded Processor

GENERAL DESCRIPTION

The ADSP-BF54x Blackfin® 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.
