The Zebra Rapixo CoF PCIe Host interface is capable of high-speed DMA transfers to Host memory, or other memory mapped onto the PCIe bus. The DMA write engine of the Host interface is capable of performing the transfers without the help of the Host CPU.
DMA write performance is chipset and computer dependent, and is slightly affected by the image size and alignment in Host memory.
The Zebra Rapixo CoF Host interface has four DMA write contexts, which act independently, simulating four DMA write engines running in parallel. The presence of multiple DMA contexts does not change the maximum bandwidth, but can help reduce latency.
