Re: Fully unrolled RC5 on FPGA

Layout for one of these chips for a 3.3V 32bit PCI is a long days work.
I tend to use pcb on sf.net, an older version that's pretty fast. My
local PCB house is pretty reasonable with 1 wk turn on 6 layer. If we
keep this a pretty simple card (small pci form factor) they would be
pretty cheap in a short run.

Question is, what else would people want on the card ... SRAM? SDRAM?

Other than layout time and increased board size, isn't much cost to
adding a few simple things. I'd suggest configuring it from a small
JTAG PLD tied to a CF socket on the back panel. That way you can
easily change it's code by swapping CF cards when it's dead, and when
it's working, write the CF from a PCI utility thru the FPGA.

Will have to check that XCV4's can actually be connected to a 3.3V PCI
bus directly. May have to use an older FPGA as the PCI bus controller.

As for PCI express, that's not a hobby project ... some serious engineering
and significant IP in cores.

	Me too, considering what you were saying in the past.
	I'm going to bet that there would be a dozen people interested in PCI
	boards. Much more if it was versatile for other applications (it would
	be dumb not to).
	I assume the V4 has LVDS for PCI express applications. It might make the
	board cheaper/smaller.
