Abstract:

This paper focuses on the design of FPGA-based PCI bus data acquisition.The board has realized reading data by means of enquiries,interrupt and DMA.It not only acquires real-time data,but also achieves high-capacity data cache,which can effectively meet the requirements of high-speed data acquisition and transmission.As a result of the utilization of FPGA,the product development cycle is shortened.The design can also be modified and upgrade online.

Key words: FPGA;PCI;data acquisition
