设计了ARM与DSPHPI(Host Port Interface主机接口)的通信接口,并通过该接口完成了ARM对DSP程序的动态加载。该方法减少了DSP对于外部非易失性存储器的需求,同时提高了DSP加载方式的灵活性,对于软件无线电波形组件的动态加载有重要的意义。
This article designs the communication interface between ARM and DSP HPI. The ARM processor can dynamically load the DSP program through this interface. This method reduces the requirements of external nonvolatile memory, and improves the flexibility of the DSP boot mode, which is also important for the loading of the software defined radio waveform components.
