As usually you have to begin with what you need. Will it be using an external DMA engine or will it have one built into it? If you've got a DMAC core already, it will define your V4L2 dma operations choice - contiguous or SG, unless, as Steven mentioned, you go over USB. Then you decide what sensor interface you need - parallel or CSI, etc. > Are you using a USB or PCIe controller to talk to the fpga, or does > the fpga contain embedded IP cores for USB or PCIe?
