+ * Those code should be works fine with V2 and V3 bitstream of Icarus.
+ * Operation:
+ * No detection implement.
+ * Input: 64B = 32B midstate + 20B fill bytes + last 12 bytes of block head.
+ * Return: send back 32bits immediately when Icarus found a valid nonce.
+ * no query protocol implemented here, if no data send back in ~11.3
+ * seconds (full cover time on 32bit nonce range by 380MH/s speed)
+ * just send another work.
+ * Notice:
+ * 1. Icarus will start calculate when you push a work to them, even they
+ * are busy.
+ * 2. The 2 FPGAs on Icarus will distribute the job, one will calculate the
+ * 0 ~ 7FFFFFFF, another one will cover the 80000000 ~ FFFFFFFF.
+ * 3. It's possible for 2 FPGAs both find valid nonce in the meantime, the 2
+ * valid nonce will all be send back.
+ * 4. Icarus will stop work when: a valid nonce has been found or 32 bits
+ * nonce range is completely calculated.
