According to the specifications of MHAL in the system of software communications architecture version 2.2.2(SCA2.2.2), this paper proposes s a MHAL design method based on FPGA with RapidIO IP core, which separates the FPGA waveform design from the specific hardware platform. High reliability and low latency RapidIO bus is used for hardware platform interconnection. The function and performance has been verified through simulation software and hardware platform. There is a great reference value for practical application.
