Re: Vector Task Group minutes 2020/12/04
8 Maks registers are quite needed in modern outer-vectorized loops. Also in graphic shaders. I would say 16 is overkill. Now, and I am not defending this, if we had to go this route, I would seriously fight for masks-in-x-registers. I.e :no new state , no new instructions. Only a few arch tricks to try to avoid loss of decoupling between vector unit and scalar unit. That’s better than a new set of registers and instructions Roger.
