Based on analysis of the timing of VME bus,a VME slave interface was designed by introducing FPGA.Utilizing the characters of low-development cost,low power consumption and high density of FPGA and the idea of compact design,the double port RAM and timing control module were integrated in one chip of FPGA to realize the communication function of VME interface.The whole design is flexible and costless.The results of system simulation and prototype test show that the VME interface works reliably and easily.
