Design of Data Acquisition and Storage System Based on the FPGA

AbstractAiming at a storage system of high-speed data acquisition, it is designed with 6 channel,16-bit AD converter chip AD7656 and a programmable logic device EP2S90F102.The K9W8G08U1M chip made in SAMSUNG is selected as storage unit, and FPGA controls the needed logic for FLASH and AD converter. At the end of data acquisition, the stored data can be transmitted to the host through the USB2.0 interface. Because of the importance of the power supply, the designs of power supply controller are given
