Re: Wishlist for next revision of Epiphany ISA
Posted: Thu Aug 07, 2014 2:24 pmNotice that the instructions in the delay slot(s) are already in the pipeline.We just start fetcthing from the new address(when the branch has been decoded)and we execute the instructions in the delay slot(which are already in the pipeline) and remove the remaining wrongly fetched instructions.This improves speed because fewer instructions are wrongly fetched.
