Hi
The logic design has two SHA cores in it for each "hash" engine and runs fully pipelined. I can see in the simulation that the first hash takes 2 clock cycles, and then a new hash/nonce attempt is generated each clock cycle after that. It seems like that if no solution is found, that the code in cgminer drops the request and then its not counted as a hash attempt?
I just a single serial interface and no queue running. Maybe the issue is job-to-job latency? I need to implement the queue to make sure the chip has continuous work
