I am not familiar with skewed pipes, but nonetheless the properties of the belt and the special Mill instructions like retire gives the opportunity for a new class of pipelining not seen before and with a 3 times higher IPC.
- deepnotderp 9y agoThe belt is indeed interesting, but note that it precludes OoO should they choose to add it at a later time. I'm not entirely optimistic about the belt because basically the same thing exists on the Mali gpu (albeit not publicly documented to the best of my knowledge) and it suffers from saturation issues. The issue with ilp extraction for VLIW compilers has historically been the difficulty of drawing accurate traces through branches to get sufficient ilp. Nothing the mill has shown so far addresses this.
