ADSP-2104集成电路（IC）的DSP（数字信号处理器）规格书PDF中文资料

ADSP-2104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-2104DSP（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-2104 and ADSP-2109 processors are single-chip microcomputers optimized for digital signal processing (DSP) and other high speed numeric processing applications. The ADSP-2104/ADSP-2109 processors are built upon a common core. Each processor combines the core DSP architecture— computation units, data address generators, and program sequencer—with differentiating features such as on-chip program and data memory RAM (ADSP-2109 contains 4K words of program ROM), a programmable timer, and two serial ports.
