Design of serial communication interface based on FPGA

As the key processing equipment of comprehensive task processing system, Mission management computer needs to crosslink with various equipments, and the types of communication interface are different. A serial communication interface based on FPGA (Field Programmable Gate Array) has been designed in this paper, used for data communication with other equipment. It guarantees the realization of the serial communication function under the condition of without any increasing in hardware resources. It accords with hardware equipment standardization principle. The design is adopted the Xilinx Company´s Virtex-4 series FPGA chip, simulation results indicate that it satisfies protocol requirements.
