In the paper,the composition,working principle and working mode of QSPI integrated in TI's Sitara series AM437x processors are introduced.And the QSPI protocol is analyzed,the existing IP resources are used to describe the QSPI interface with Verilog HDL,and complete the independent design of the QSPI interface with the support of the EDA tool.At the end,the simulation verification platform is built,and the simulation verification is performed by connecting the serial NOR Flash to the QSPI interface for communication,and it passes smoothly.
