Hi all. I am looking at creation of a PCI-based card at the moment, but I may need more bandwidth than PCI can supply 1) Is it possible to extend the PCI core to work on PCI-X (64-bit, 133MHz) easily? Or has anyone worked on this before? 2) Does anyone here know much about PCIe? I understand the basic architecture, but I don't have access to the specs. My main question with regards this is: Is it possible to just, say, interface 4 1xPCIe devices to a 4x PCIe slot, or would some form of switch be required? Specifically, could I take 4 PCI-PCIe bridge chips, link each to a separate PCIe lane, and have 4 separate PCI busses?

Karl Xilix makes a bunch of solutions for both PCI (64) and PCI-E. You can choose if you want to run parallel or serial. I preferr to use soft-cores because you can relocate the core in any programmable device you would like. However, Xilinx has several solutions where the hard-core is built in. These solutions are very economical to implement if you are using software such as Altium.
