英文摘要：

The design of a McBSP interface based on FPGA is introduced in this paper ,aiming at the McBSP serial communication between Testboard and Processor of the Radar Signal Processor. The function of the McBSP interface ,the principle and the design of key circuit are introduced. In addition, the logical program, allocation and the communication process among modules are analyzed respectively. It is proved that the McBSP interface based on FPGA can satisfy the project demand completely, and it is also suitable for the communication between Tesboard and the Radar Signal Processor.
