DMA (direct memory access) transmission method, device and equipment based on PCIE (peripheral component interface express) bridging mode

The invention relates to the field of data services, and provides a DMA (direct memory access) transmission method, device and equipment based on a PCIE (peripheral component interface express) bridging mode. The DMA transmission method based on the PCIE bridging mode comprises the steps that an IP core of a standard PCIE of a high-speed serial computer expansion bus is configured to be in a bridging mode; querying a register on a logic side through a main interface to obtain an idle/busy state, and issuing information of downlink data to be moved to the logic side; and initiating a memory read operation through the slave interface, and receiving data corresponding to the memory read operation through the logic side and the slave interface. According to the method, the logic resource consumption is reduced, the development and later maintenance difficulty is reduced, and the method is suitable for multi-service-type scenes. 本申请涉及数据业务领域，提供一种基于PCIE桥接模式的DMA传输方法、装置及设备。所述基于PCIE桥接模式的DMA传输方法包括：将高速串行计算机扩展总线标准PCIE的IP核
