DSP主机接口与ARM的互连设计

Design of connection between ARM and DSP through HPI

本文讲述了一种通过DSP主机接口实现ARM与DSP数据交换的接口互连技术,并给出了硬件连接图和软件实现说明。该方法不仅能满足数据传输速度的要求,而且连接简便,软硬件开销小。

This paper proposed an interface connection technique to realize data exchange between ARM and DSP through HPI. Moreover, the hardware circuits and software realization are presented. This method can not only totally meet the needs of the embedded OS, but also can be carried out easily with little cost of hardware and software.
