摘　　要：DSP是与数字信号处理紧密相关的一种特殊的微处理器。它具有强大的数字信号处理功能,同时需要从外部处理器加载用户代码来实现程序的启动,文中以BF533为例介绍了ADI BF53x系列DSP通过其SPI口实现程序加载,同时介绍了相应的硬件电路和软件设计、调试等。该方法灵活性高,节约资源,具有较强的实用性。DSP is a specific microprocessor, which is closely related to digital signal processing. It has strong function in digital signal processing in which the procedure runs through the procedures-load from external memory. In this paper, we introduce the procedure-load via SPI port of DSP, which belongs to the ADI BF53x line and the corresponding design of the system＇s hardware and debugging of software and so on. With high flexibility and requi- ring few resources, this method is highly practical.
