In order to realize the data of software simulation through PCI bus DMA transmission, and convert it into high-speed video serial data stream (LVDS data stream) after processing, a data conversion module based on PCI9054 is designed. By introducing the performance and characteristics of PCI bus interface protocol chip PCI9054, the characteristics of Windows WDM driver are analyzed. In the software and hardware design, the data buffer is set as two groups of SRAM structure, and the two groups of SRAM alternately access data, which effectively overcomes the phenomenon of discontinuous data flow and solves the problem of data discontinuity between forming uninterrupted data flow and two DMA transmissions. The application results show that the design can meet the conversion and transmission of LVDS data stream within 20 MHz of digital video bandwidth.
