The price for a Virtex 4 FX12 FPGA  (10K flip flops, 648Kb Block RAM,
1 PPC405 core, dual 10/100/1G ethernet MACs, etc)  close to $200 each.
 Expensive if all you need is a processor, but I already have a lot of
custom interface logic in the FPGA so adding a few $$ extra for the
PPC core isn't a problem.  I also have the luxury of extremely small
production volumes, so component cost is dwarfed by the cost of
development.


Power is going to depend on what you put into the FPGA and how fast
you clock it.  Xilinx quotes 0.45mW/Mhz for the PPC only.  That equals
135mW at 300 Mhz.  My design will probably top out at 2W for the FPGA.

I use both, but this project will be in VHDL.  VHDL has some nice
features and seems to actually be gaining strength over Verilog.
