ADSP-21477集成电路（IC）的DSP（数字信号处理器）规格书PDF中文资料

ADSP-21477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-21477DSP（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。

The ADSP-2147x processors are available with unique audio-centric peripherals, suchas the digital applications interface, serial ports, precision clock generators, S/PDIF transceiver, asynchronous sample rate converters, input data port, and more.
