|
* 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. |

// the full nonce range, so to avoid being idle we must abort the |
|
// work (by starting a new work) shortly before it finishes |
|

|
// Thus we need to estimate 2 things: |

// 1) How many hashes were done if the work was aborted |
|
// 2) How high can the timeout be before the Icarus is idle, |

// to minimise the number of work started |

// Tn = Total time in seconds to calculate n hashes |

// Xn = number of hashes |
