A PCI Express bus adaptive multi-interface design method based on an AXI4 interface

The invention provides a method for adapting a PCI Express bus adaptive multi-interface design metho based on an AXI4 interface. The method is characterized by comprising the following steps: a conversion step: a PCI Express bus is connected with a Local parallel bus through an AXI4 interface so as to realize conversion from the PCI Express bus to the Local parallel bus; And an adaptation step: the Local parallel bus is connected with external interface equipment to access the peripheral resources. Through application in practical engineering, the method can enable the PCI Express bus to correctly and reliably access the multi-interface device. 本公开提供种基于AXI4接口的PCI Express总线适配多接口的方法，其特征在于，包括以下步骤：转换步骤：PCI Express总线经由AXI4接口与Local并行总线连接，以实现PCI Express总线到Local并行总线的转换；适配步骤：将Local并行总线与外部接口设备连接，以访问外设资源。通过实际工程中的应用，该方法能够使PCI Express总线正确可靠的访问多接口设备。
