Abstract
This paper introduces a new structure of DMA control er based on FPGA high speed transmission system with PCI Express 3.0, explains the logical design of DMA control er in detail and packages it into a standard FIFO structure, which can conveniently adopt to data acquisition or playback system. In order to verify the function and reliability of the design, a high-speed data acquisition and playback system based on PCI Express 3.0 X8 channel is built. The experiments show that the performance of the system has achieved the design specifications. The read/write speed of PCI Express 3.0 X8 channel DMA control er can reach 4,900MBytes/s when the size of the DMA is 16MB, which can meet the transmission needs of most of the high-speed data acquisition and playback systems.关键词
