Xilinx has embedded PowerPCs inside Virtex-II FPGAs. SDRAM interface is
certailnly possible to arrange on that kind of FPGA, if you need. PCI is
certainly possible to achieve at a cost (money or blood, sweat & tears).

For more info go see the site below.

Probably not for this one. Anything commercial and good enough to handle
these big FPGAs will cost you dearly. Without any detailed knowledge I
would guess you will end up at about 10 to 20 kUSD (or more) for a profes-
sional design kit (e.g. Synplify HDL synthesis, Xilinx ISE place & route,
ALDEC AHDL simulator, all these Win blech :) The more *IX you want the
more bucks you have to pour into it. I know about gEDA and Icarus
verilog, but have so far had no luck...

We are all admitted to have an opinion, no matter how unpractical... ;)

Good luck.
