The Study Of High-Speed Data Acquisition System Based On USB2.0

With the development of modern industry production and science research,the data acquisition face new challenge. In instantaneous test or image transact,we need data acquisition system with high-speed. Now most of high-speed data acquisition adopt PCI or ISA technique, and they have some defects like as complex; expensive; unexpanded; electromagnetism disturb etc. To solve these problems, the thesis researches high-speed data acquisition system based on USB2.0. There are some contents are presented as follow: researching how to use USB2.0 to high-speed data acquisition; programming device driver of USB based on WDM model; programming GPIF's firmware of FX2 of Cypress Company; designing circuit of the high speed data acquisition. The thesis purpose and design the high speed data acquisition system based on USB2.0 , and the whole system have been verified in application.
