High-speed Data Acquisition and Processing System Based on DSP and FPGA

In order to acquire the data accurately and rapidly,a multi-channel real-time acquisition system based on DSP,field programmable gates array(FPGA)and ADS8364 was proposed.This system mainly acquired analog signals by ADS8364 controlled by FPGA,then DSP pretreated these signals and communicated with PC through the CAN bus,which realized the data storage,processing and display.This system can improve precision by using the multi-point detection and data fusion.This system is of simple structure,high speed,high reliability and high accuracy,which has a broad prospect of application.
