ADSP-BF538集成电路（IC）的DSP（数字信号处理器）规格书PDF中文资料

ADSP-BF538属于集成电路（IC）的DSP（数字信号处理器）。由亚德诺半导体技术有限公司制造生产的ADSP-BF538DSP（数字信号处理器）数字信号处理器是类似于微处理器或微控制器的器件，但区别在于其内部架构经修改，适用于对连续数据流连续执行以乘法和加法运算为主的算法，而不是以条件逻辑或大量并发进程为主的算法。该器件通常用于诸如音频或视频信号处理等应用。

GENERAL DESCRIPTION

The ADSP-BF538/ADSP-BF538F 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.
