Subject: Katja's weekly report #15


I wasn't able to work yesterday and I won't be able to work today, I caught
a flu.

1. Updated wiki page
2. Fixed bug so that bcrypt on FPGA doesn't fail self test on first run
3. Partially optimized bcrypt on FPGA
       - using true dual port RAM for Sbox with two cycle latency. In
simulation I have it with 1 cycle latency, 3 cycles per BF_ROUND and
1709766 cycles in total but it doesn't work on ZedBoard.

I will be moving to a new place this week and I won't be able to do much
work but I will list here everything I can think of at the moment

1. Finish optimization - it's about figuring out why having 1 cycle latency
RAM doesn't produce correct result and figuring out clock problems
2. Implement multiple bcrypt cores in FPGA
3. Replace mmap() calls in BF_fpga.c with proper drivers
4. Try to get bcrypt on 64-core Epiphany to work

Best regards,
