You cannot even fit 1 sha-1 core in your coolrunner cplds, they are too "small" and does not have enough macrocells.
The only way to beat the GPUs is to make custom SL3 asic. |
Thanks a lot for the info.
The PCB itself isn't a problem, XBox360 RGH solution is on a small board, QFP package, with JTAG pin-header.
But, you say that it's too small for SHA1 code, so I'll forget about CPLD.
Can you give me some details about how much macrocells/memory should a CPLD/FPGA have for SL3 calculation? I've actually just started learning about these devices, and SHA1 calculation isn't really a complex task, so I'd like to get something capable of doing it.
I have just two SL3 phones that are just fine now, sim-locked, but if I could unlock them and learn something along, it would be nice.
Of course, I wouldn't ruin (your) SL3 market, something with 2-3G/s (FPGA speed I found on this forum) can't catch up with 4x7970 *******s calculating >14G/s.
