I'm new to the AXI interface. According to the datasheet, the PCIe core uses the AXI-Stream interface. (The Xilinx AXI4 Interface page says this is unidirectional? PCIe is bidirectional; am I missing something here?) Anyways, I have some custom IP I want to interface to (read/write some registers). I'm looking at using the "Create Peripheral Wizard" in XPS, but it only lists AXI4 and AXI4-Lite. Are either of these compatible with the AXI-Stream interface or am I approaching this the wrong way?

Possibly; when is the expected release? This is a "down the road" project, but I'm not sure how far down the road. I think I've found a workaround in the meantime, creating my core in EDK and instantiating it and the PCIe core in ISE (although connecting them together will be manual). I haven't tried it yet. It'll be a little more complicated but at least I'll be more experienced with AXI and dealing with the IP cores =P.
