Abstract: Deskew and data reorganization are core difficulties of implementation of SPI4.2 interface within FPGA. According to the analysis of skew principle and data reorganization principle, the design and implementation solution based on FPGA is given, and the hardware schematics of key part are shown. The online test results prove that the solution can realize SPI4.2 interface functions.
