This readme does a really poor job of explaining what the improvement is or how they drop half the multiplications. What is the Big O run time on this? Is this shifting the known best bounds?

And the diagrams are chaotic and don't really explain anything about why this approach is fast or good. The result is that I'm reluctant to even click-through to the PDF.

If you want to improve the project credibility please consider being honest and open about what is actually going on and giving some clear explanations and illustrations, rather than things that may as well be designed to hype people too busy to tell you that you are cranks. It's hard to tell if this is incredibly groundbreaking or just but nothingburger. Sadly I almost feel like that must be an intentional decision motivated by poor merits of work and a desire to exploit AI height. The alternative - which I prefer to believe is the case - is that the author simply needs to revise and better contextualize.

It´s actually fairly clear

This looks pretty cool! What's the catch? e.g. why isn't this already implemented in accelerators, is it really just a forgotten algorithm, or this has some implications on the cost of building the accelerator or else?

IMHO, for fixed-point MM accelerators, there is no catch, I think it's an overlooked algorithm. It's based on an algorithm by Winograd who coincidentally also proposed another unrelated algorithm that later became very popular for CNN acceleration which would take some visibility away from this other algorithm by Winograd... But that is speculative

Perhaps it's less of a hidden gem and more of a spotlight moment.

Not to everyone. If it's clear to you, you could helpfully explain it.

The readme doesn't explain much, but the introduction to the paper itself is quite approachable.

As for whether it's groundbreaking or not ... it's a neat readily-accessible constant-factor improvement for area-constrained fixed-point accelerators. That doesn't change everything overnight, but neither is it nothing. It's nice work.
