avalon asic - communications protocol - diy designs

[chaoztc]

sorry for posting here - but as a newbie I can only post here.

the avalon-ref implementation could be found on github.
there's also a spec of the asic itself.

but in the spec the bit-sizes of each value from the communications protocol is missing
and the pseudo-code snippet does not explain how the array w is precalculated.

some ideas how to get a working precalc-code could be found in following github projects:
