Design and Verification of Anti-radiation SPI Interface in Dual Mode Satellite Navigation Receiver Baseband Chip
This paper designs the SPI interface module in the baseband chip of the dual mode satellite navigation receiver based on the AMBA bus, and this paper is based on the first edition of the baseband chip accepted by the Science and Industry Corp. This design provides the IP core of SPI for the SoC using the LEON series processor and uses the TMR on register transfer level and evaluates the final results after the reinforcement. The results of verification and evaluation show that the SPI master designed by this paper can communicate normally based on the AMBA bus, and the SPI master after reinforcement can resist SEU to a certain extent and improve its stability in the space radiation environment.
