摘　　要：主要介绍了一种基于DSP的数据压缩系统的硬件电路的实现过程,文章把整个硬件系统分成2个模块来介绍:数据采集模块以及DSP解算模块。数据采集模块采集前端信号在CPLD的控制下经过AD和FIFO把数据写入DSP解算模块,DSP接收到信号后,把数据进行压缩。每个模块从核心器件的选择、硬件电路的总体设计方案以及实现过程进行了介绍。实验表明该方案是行之有效的。the article introduce the hardware design of data compression technology of remote measurement based on DSP, in the article, the whole hardward system was divided into two modules： Data acquisition module and DSP algorithm module. The data acquisition module receives the data and transport the data to the DSP algorithm module through the AD and the FIFO write data under the control of the CPLD. The data were compressed after DSP receives the signal.The choose of components and design program of whole hardware and Implementation process was introduced in every module. Experiments show that the program is effective.
