基于EHPI的DSP与ARM通信接口设计

Design of the Communication Interface between DSP and ARM Based on EHPI

随着嵌入式技术应用的不断发展,对高速数据处理、精确控制和多芯片协作提出了更高的要求,芯片间协作通信问题日益凸显。本文通过使用ARM的GPIO接口仿真数据总线,与DSP的EHPI接口通信,实现了控制器ARM对数字信号处理器DSP内存数据的读写操作。

With the continuous development of embedded technology, higher requirements are raised for high-speed data processing, precise control and multi-chip collaboration, and inter-chip communication issues become increasingly prominent. In this paper, using the ARM GPIO interface simulation data bus, and DSP EHPI interface communication, the read-write operation of digital signal processor （DSP） memory data by the controller of ARM is realized.
