| Abstract: | The paper describes a data acquisition system using EP1K50 serials FPGA, AD7656 A/D coveter and NAND Flash. The system achieves acquiring analog signals with the throughput rate up to 250 kS/s and the precision 16 bits and also storing data which transfers through PC104 bus to the host. The design scheme of the data acquisition system based on FPGA 、 flowchart, as well as the realization of steps key module are presented. |
