| Abstract: | A hardware structure of data-sampling card based on PCI bus is introduced.The design method of interface between the PCI2040 and the HPI of TMS320VC5402 are described.The basic theory and development method of Windows Driver Model(WDM) driver for PCI card is explained.The operation of memory access,interrupt serve,and communication between application and driver are recommended.Experiments prove that the system can satisfy the requirements of real-time and high transfer speed of large amount data.. |
