In this paper, a high-speed data acquisition system based on the technology of USB2.0 (Universal Serial Bus) is designed, in which USB master logic is implemented in an FPGA (Field Programmable Gate Array). Firstly, the hardware of data acquisition system is discussed, which includes chip selection, data acquisition and transmission circuit and power conversion circuit. Secondly, the corresponding software including USB firmware program, USB device driver and application program as well as its modifications have been described. The designed hardware and software will help to achieve a data acquisition system with the characterstics of high speed and high accuracy, etc.
