Abstract


With the rapid development of large scale integrated circuits and computer technology , digital signal processing technology has been widely applied . Signal and information processing system , the data acquisition system is an integral part . Real life physical signals are analog signals , the analog signal into a digital signal for digital signal processing and analysis of the premise . , Digital signal processing , real-time requirements getting higher and higher , we need high-speed data acquisition system to extract the information , the data transfer rate of the data acquisition system put forward higher requirements . This paper design a model directional machine data acquisition board hardware and driver software . Multi-channel data acquisition system based on PCI bus design . The system has five channels , each channel has the acquisition rate of up to 40MHz , the continuous acquisition capacity of 12 sampling accuracy as well as the 108KB memory depth . The paper gives the overall scheme of the data acquisition system , and discuss the data acquisition card for analog-to-digital converter module , memory module , logic control module , PCI interface module , etc. , including the chip select methods and precautions . PCI bus and PCI bus dedicated interface chip PCI9054 -depth study of the design and implementation of the WDM model driver .
