Yes, X11 is a composite of 11 algos, but the hardware is designed to give you the result after running through all those algos. You can't just tell the hardware to stop in the middle of computing and give you the results for a specific algo. ASIC's usually are optimized and made very efficient at doing 1 specific function, in this case x11. To add or do only a specific algo requires not only a firmware change, but now also a hardware change.
Are you working in Bitmain?
The ASIC core parameters have not been published !!
How do you say these statements?
If you know anything about it, tell it ... otherwise it's useless ...
What the guys try to do is a reverse engineer ... since Chip data is not public ...
Chip on L3+ ---> BM1485
Chip on S9 ----> BM1387
Chip on D3 ----> BM1760 ??
Now ... have to read the PIC (PIC16F1704) data, for understand commands that a PIC make on each of the 3 boards of the D3 ... and understand the instructions that the Chip Asic accepts them ...
and then you can make a verdict ...
