Best peripheral/interface to use for transmitting data from PCI Express to the OMAP-L138

Other Parts Discussed in Thread: OMAP-L138

Hi --

I sort of asked this question in a previous post, but you had to read through my evolving thought process to get to it.  So here it is on its own.  Anybody have any idea the best peripheral to use to transfer data from an external device via PCI Express?  I'm thinking conceptually of having a PCI Express endpoint manager on a card that connects as directly as possible (don't know what logic, if any, might need to sit in between) to the OMAP-L138 board.  From the OMAP-L138 board's persepective, what is the best interface to use to transmit/receive as high-speed as possible (a full 16 lanes of PCIExpress is capable of transferring 5GB/sec) data via a PCIExpress connection to another host processor.

If anybody has any thoughts onthis, I would love to hear them.

Thanks.

Mike

    USB would probably be the easiest out of the box method, as I believe I have seen USB to PCIe 1x adapters out there used for accessing netbook SSDs outside of the netbook, though I am not sure how easily this would really apply to your situation, particularly if you needed a PCIe 16x interface.

    For higher rates you would probably be looking at some sort of FPGA implementation outside the L138 to adapt between the PCIe and an interface the L138 can understand, possible contenders at this point would probably be SATA, uPP, or the video interfaces. Which would be most appropriate would likely depend on how your data will be flowing through.
