Design and Implementation of Multi-channel Synchronous Data Acquisition System

Zhijun Han

Abstract

Multi-channel synchronous data acquisition system based on DSP and CPLD is designed. The system is constituted by multi-channel synchronous data acquisition module and DSP data processing module. Multi-channel synchronous data acquisition module can realize simulatneous test of the related signal and receive the related information after being analyzed. Data processing module can implements data processing and the related functions of the algorithm. The experiment on the data compression algorithm embedded in DSP indicated that this system can satisfy multichannel synchronous data acquisition and processing requirements, and its performance is secure and reliable.
