摘　　要：HPI接口是为了解决多DSP之间数据共享而设计的,详细地介绍了HPI接口的外部硬件接口信号及控制寄存器,并给出了一个双DSP的接口电路及控制程序,方便快捷地实现了数据读写功能,由于HPI接口的简单、快速、不占用系统工作时间的特点,为多DSP的并行信号处理提供了一个硬件环境.HPI interface is designed for resolving problem of data share between multiple DSPs.Hardware signal and control registers of 54X series of the HPI produced by TI company were illuminated .As an example,a dual DSPs circuit and control program to read and write data in convenience were given.Because of HPI's simpleness,speediness and no-wasting system time characteristics,this interface provides a good hardware condition for parallel process between multiple DSPs.

关 键 词：数据通信 数字信号处理器 并行处理 数据共享 HPI接口 多片DSP
