Interesting, I would like to try it out too. Any plans to make the hdl open source ?
No. But, if there is interest, I will describe how I did it and maybe answer questions. I don't like to give away answers... at least not for free. But I am happy to help people who wish to learn.
Do you have a miner that you tweaked? I've heard good things about your bins.
Yeah, I rewrote both the CPU and GPU implementations of Blake-256, did a bunch of mods, fixing one possible integer overflow, reducing CPU usage by 3x - 4x, and, of course, modified the kernel enqueue to take my custom kernel. Also modified what is passed to the kernel, and how it's passed, which is why this was necessary. Added a 64-bit target, too, so it doesn't waste CPU time returning every share that meets diff 1.

Already replied.
Where we can download binaries whit your implementation?
I haven't released it.
EDIT: If done correctly, the CPU usage can be almost eliminated - however, this would require edits to code that the Decred team are likely to modify in the future for other reasons, and I'd rather not have the pain in the ass of merging.
