Method for writing data from AXI bus to OPB bus and method for reading data from AXI bus to OPB bus

Abstract

The invention discloses a method for writing data from an AXI bus to an OPB bus. The method comprises the following steps: receiving AXI write data sent by the AXI bus, wherein the AXI write data is stored in an AXI write cache; performing time sequence conversion from an AXI bus protocol to an OPB bus protocol on the AXI write data to obtain OPB write data; and exporting the OPB write data from the AXI write cache to an OPB bus. By applying the data writing method from the AXI bus to the OPB bus, data interaction between the AXI bus and the OPB bus is completed, the cost is reduced, and the project development efficiency is improved. The invention further discloses a data writing device from the AXI bus to the OPB bus, a data reading method and device from the AXI bus to the OPB bus, electronic equipment and a storage medium, and the corresponding technical effects are achieved.

Description

technical field [0001] The present invention relates to the field of storage technology, in particular to a method and device for writing data from an AXI bus to an OPB bus, a method and device for reading data from an AXI bus to an OPB bus, electronic equipment, and a computer-readable storage medium. Background technique [0002] With the continuous development of large-scale integrated circuits, the design methods of integrated circuits (Integrated Circuit, IC) are also gradually optimized, and the multiplexing of resources based on intellectual property (Intellectual Property, IP) can improve the system on chip (System On Chip, SOC). ) efficiency and reliability, save design cost, and shorten the time to market. [0003] The Advanced eXtensible Interface (AXI) bus can meet the requirements of the new generation of SOC systems for high performance and low power consumption, and has been widely used. On-chip Peripheral Bus (On-chipPeripheral Bus, OPB) is widely used in th...

AI Technical Summary

Problems solved by technology

In the process of chip design and development, it is often necessary to use mature intellectual property rights based on the OPB bus protocol in the AXI bus system, but when performing data interaction between the AXI bus and the OPB bus, design and verify these intellectual property rights again The work will take a lot of time and labor costs, reducing the development efficiency of the project
