摘　　要：DSP是针对数字信号处理需要而设计的一种具有特殊结构的微处理器。它需要通过程序加载来进行信号处理,本文通过具体实例介绍了sharc系列的DSP通过其SPI口的程序加载,同时也介绍了相关系统的硬件设计和软件的调试。该技术可靠性高,使用灵活方便,具有很强的实用性。DSP is designed to meet the need of Digital Signal Processing as a specific structuralized microprocessor, in which the signal processes through the procedures-load. In this paper, we introduce the course of loading the procedures via SPI port of DSP, which belongs to the share line, and also the relevant system＇s design of hardware and the debugging of software is introduced. With flexible and convenient, this method is of high reliability and highly practical.
