Regardless, this is not the place for such pie-in-the-sky discussions; if you want to theorise about weird and wacky computer architectures then please take it elsewhere. It's hard enough to get it right when there's a single instruction set, as with Arm's big.LITTLE. For example: https://www.mono-project.com/news/2016/09/12/arm64-icache/ I've also heard of problems of programs crashing due to instructions supported on one core type not being supported on the other. -- Rebecca Cran
