ADSP-2184N集成电路（IC）的DSP（数字信号处理器）规格书PDF中文资料

ADSP-2184N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-2184NDSP（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-218xN series consists of six single chip microcomputers optimized for digital signal processing applica tions. The high-level block diagram for the ADSP-218xN series members appears on the previous page. All series members are pin-compatible and are differentiated solely by the amount of on-chip SRAM. This feature, combined with ADSP-21xx code compatibility, provides a great deal of flexibility in the design decision.
