xapp859-PCIE接口的DMA存储方式硬件设计
资料介绍
This application note provides a reference design for endpoint-initiated Direct Memory Access
(DMA) data transfers using the LogiCORETM Endpoint Block Plus for Virtex@-5 FPGAs. The reference design targets the ML555 hardware platform and uses the on-board DDR2 memory for storing DMA data. The design illustrates how to create an 8-lane endpoint design with an interface to a DDR2 memory. The reference design can also target an ML505 hardwareplatform to showcase DMA performance in a 1-lane endpoint design.A driver and GUl application are provided to allocate and initialize a system memory buffer in the host PC and set up DMA transfers. The design demonstrates how to transmit and receive transaction layer packets as a DMA initiator as well as respond to target transactions.
