With concise protocol,simple networking,deterministic delay and other outstanding features,reflective memory network has been widely used in the hardware-in-loop simulation system and distributed control system.According to the networking request of ring reflective memory network,developed a reflective memory network interface board with CPCI interface to achieve the function of network link layer and physical layer.At the same time, the driver under Windows XP operating system is designed and developed, and the function of software layer is realized in the form of API function. Also, during development, reflective memory network test environment is built and a series of tests are made.Experimental results show that the CPCI bus based reflective memory network interface board is stable,reliable, and fast data update rate.The experimental results also show that the selection of DMA or read and write way should be based on the reflective memory network transmission frame number.
