The Study On The High-Speed Data Acquisition Card Based On PCI Bus

The high-speed data acquisition system as the base of modem signal and information processing is developing very quickly with the appearance of the new A/D conversion chip.But the universal data acquisition system is so expensive ,thus designing a high performance high-speed data acquisition system using A/D conversion chip and easy circuit is always the target of engineer . This paper introduces a kind of high-speed data acquisition system based on PCI BUS.The situation of current data acquision field is discussed in the prolegomenon.Chapter two summarize the PCI BUS the data transferring mechanism and S5933 PCI controller of AMCC. Chapter three studies the design of the system architecture and interface. The circuit design and the system working theory are also illuminated by detail, chapter four studies the VxD driver based on PCI BUS. Chapter five is about the simulating and debugging. The general work of this paper is summarized and the farther research direction is pointed out in the last chapter.
