| Abstract: | This paper describes the procedure of designing Direct Memory Access (DMA) data transfer system based on Peripheral Component (PCI) bus interface technology. The system is applied to the test instrument for ladar receiver. When the ladar receiver working, the PCI interface card based on DMA data transfer system can achieve 70 MB/s transfer rates, collect and save the parameter of ladar effectively, and offer the data for computer to analyse rapidly. We emphasize the design of hardware circuit based on PCI bus interface technology and the development of PCI DMA driver program based on Windows Driver Model (WDM). |
