Method for writing data from axi bus to opb and method for reading data from axi bus to opb

Abstract

Disclosed are a method and apparatus for writing data from an Advanced extensible Interface (AXI) bus to an On-chip Peripheral Bus (OPB), a method and apparatus for reading the data from the AXI bus to the OPB, an electronic device and a non-transitory computer readable storage medium. The method for writing the data includes the following steps: receiving AXI write data sent by the AXI bus (S); storing the AXI write data into an AXI write cache (S); performing timing conversion from an AXI bus protocol to an OPB protocol on the AXI write data to obtain OPB write data (S); and exporting the OPB write data from the AXI write cache to the OPB (S). By applying the method for writing the data, data interaction between the AXI bus and the OPB is completed, the cost is reduced, and the project development efficiency is improved.
