基于FPGA和DSP的数据采集与压缩系统∗
Data Acquisition and Compression System Based on FPGA and DSP
摘要
Abstract
The test of each module function which is applied to the body of the arrow,has a special technical index for the data acquisition,for examples,the requirement of reading the data of large capacity,the error rate is extreme-ly low. By referring to the existing data collection and compression technology designs the data acquisition and com-pression system which bases on FPGA and DSP. This system can realize the acquisition and processing of 12 analog signals,the sample rate is 324 ksample/s. To compress the data through using DSP chip,the compression removal rate can reach 75%. According to the data error problems,this system comes up with the design of data stream frame transmission. Finally,the tests have been carried out,the experiments show that systematic work is stable,the system solves the problem of the unity of the performance,power consumption and speed.关键词
