The write engine is controlled through the Target Bridge. This statistics is the count of frames that are successfully transmitted. The pciexpress dma core offers a fully integrated, flexible and highly optimized solution alterra high bandwidth and low latency direct memory access between host memory and target fpgas.

Note that this buffer appears as one contiguous block in the application virtual address space but very likely lies scattered throughout the physical memory attached to the processor. It performs burst writes on the Avalon data bus.

Driver utility function definitions 5 Debug Information The driver exports debug information such as internal statistics, debug information, MAC and DMA registers etc. The read engine is controlled through the Target Bridge.
