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. > > If you are a C coder then I assume you would use Verilog I hope....VHDL is > for ADA programmers! I use both, but this project will be in VHDL. VHDL has some nice features and seems to actually be gaining strength over Verilog. -David
