A testing and training architecture HIT?TENA platform was developed by Automatic Test and Control Institute of Harbin Institute of Technology to establish virtual test system. In order to connect the testing resourse in the system,a protocol conversion module based on PCI bus and 1553B bus was designed. The logic of 1553B protocol and concurrent protocol identifi?cation were achieved on the basis of hardware structure with DSP + FPGA and FPGA. The DSP is used to realize the protocol conversion. The testing result shows the the module can perform the function of protocol conversion and reduce the delay to 1 ms. It solves the problem of low efficiency and long delay occurred when the test equipments join up with virtual test system.
