ops ... make that: Serial solution would then be (52 + 38 + 15) = 105 LUTs per RC5 engine. In addition the design would have to be wrapped with a controlling state machine and initialization storage per FPGA. Each engine would check a solution every 1248 clocks. An XC2VP70 contains just over 65K LUTS, should hold about 628 RC5 engines to check a solution roughly every clock at a speed of over 150mhz. Or roughly 75.5MKeys/sec. Currently d.net is solving 114,719 GKeys/sec. So it would take 1500 or so XC2VP70 FPGAs to match d.net's current performance. I have 33M LUT's going into my design, which should net about 314K engines, at an average speed of about 120mhz, for about 30,219,445,605 Keys/sec after burning about 17.5KW per hour. $750/mo if I let it run very long, which is highly unlikely, as the ROI is nearly zero. _______________________________________________ Hardware mailing list Hardware-Ra3b/QYEcJ3d140v2zMXi0fjHoOT/h/[email protected] http://lists.distributed.net/mailman/listinfo/hardware
