If you're familiar with how the hidden bit works for IEEE floating point, use a hidden '10' in front of the fraction for negative numbers for posits and suddenly a whole bunch of math falls out. This is equivalent to…
Oh I actually only think it's useful for machine learning. I have some unpublished, crudely done research showing that the extended accumulator is only necessary for the Kronecker delta stage of the back propagation…
Sorry, should have specified: I'm the original implementor. I'm on the paper with John Gustafson, and presenter/live-demoer of the second half the Stanford video. There is a paper coming out with details on the yonemoto…
I will say one thing: I pity the person (grad student?) that has to do error propagation analysis on a research project using posits (I'm the original implementor)
Yep. This works out to be on the order of 60x6x2 adders which is honestly not that much.
In your RTL synthesis did you use "hidden -2 bit" for negative posits? Assuming you are "cheating" IEEE by not implementing subnormals or NaN... This is one key insight that makes posit sizes much smaller, but the…
I'm the implementor for posits (deactivated my primary hn account) -- I built circuit diagrams for computation with posits. So, we have them -- and they are smaller. There is also a key insight into the representation…
