摘要
基于现实中很多信号处理系统要求处理器实时处理数据或实现各种复杂算法的同时还要能完成各种控制功能。例如语音信号处理系统。这类系统通常包括两部分:一部分为DSP子系统,主要完成信号采样,数字信号的处理及其输出等功能,另一部分为单片机控制子系统,主要完成交互界面的主控功能,如显示和键盘。这类系统既发挥了DSP的数据处理能力又利用了单片机的外围接口控制能力。这两个子系统的连接有多种方法。主要讨论了单片机和DSP之间通过DSP的HPI接口进行连接的设计方法。完成了硬件连接和软件设计方法。
Nowadays many signal processing systems require the processor to accomplish real-time data processing and kinds of control functions, such as, the voice signal processing system. This kind of system is usually composed of two parts, one is DSP subsystem, the other is MCU control subsystem. The former is mainly to accomplish the function of signal sampling, digital signal processing, and the output of the system, etc, the later is mainly to accomplish the interactive interface control function. This kind of system utilizes not only the ability of data processing, but also the ability of peripheral interface control. Connection between these two subsystems can be accomplished through many methods. This paper mainly discusses the design method to connect the DSP and MCU DSP through the HPI. Design methods of hardware connection and software are given in this paper.
