摘　　要：以Hynix公司的ARM7芯片HMS30C7202和TI公司的TMS3205416 DSP芯片为例,介绍了一个具有数据采集、数据处理、数据传输和数据显示等功能的系统。本系统工作流程如下:实时采集进来的外部数据由DSP进行处理,再由HPI将数据传给ARM进行显示或通过LAN传给服务器,实现数据远程处理功能。重点分析了DSP的HPI(host port in-terface)接口的工作原理。设计了HMS30C7202与TMS320C5416之间的HPI接口电路和HPI通信协议,给出了DSP部分与ARM部分的程序流程图。经实验验证,制作的样机满足设计要求,具有一定的实用价值。A system which possesses the functions of data collection,data processing, data transmission and data display,is introduced in this paper by taking ARM 7 chip HMS30C7202 of Hynix Corporation and TMS320C5416 DSP chip of TI Corporation as an example. The work flow of this system is as follows, the real- time collected external data are processed by DSP, then they are transmitted to ARM by HPI to display,or transmitted to server by LAN,so that the function of data remote processing is realized. The operation principle of HPI（Host-Port Interface） port is principally discussed. The HPI interface circuits and communication protocols between HMS30C7202 and TMS320C5416 are designed, and the procedure flow charts are also introduced. After verifying by experiments,our sample apparatus satisfies design requirements and has some practical values.
