摘　　要：在通用数字信号处理中,DSP具有强大的数字信号处理能力,但其控制能力不足,通常采用HPI与主机组成系统解决此问题。本文以TMS320C5416为例,介绍了DSP芯片HPI(host port interface)的组成及功能,并以AVR ATmega128L单片机作为主机,重点研究一种灵活通用的HPI与主机之间实现数据互传的硬件连接方案和软件实现方法,实现了主机通过HPI对DSP的程序引导。In general digital signal processing, although DSP is a powerful digital signal processor, it has disadvantage of controlling capacity. It is solved by the system composed of HPI and MCU. Taking example for TMS320C5416, the configuration and function of HPI were introduced. Then, a smart and general way of data share and transmission between MCU and DSP through HPI was researched. In the end, an application of HPI in the program boot-loading of DSP was given.
