What exactly is the lesson of Itanium is debatable. > Q: I feel like deja vu - at Hot Chips, Intel introduced VLIW-concept Itanium that pushed complexity onto the compiler. I see traces of that here. What are you doing to avoid the Itanium traps? How will you avoid IP from Intel? > A: Itanium was in-order VLIW, hope people will build compiler to get perf. We came from opposite direction - we use dynamic scheduling. We are not VLIW, every node defines sub-graphs and dependent instructions. We designed the compiler first. We build hardware around the compiler, Intel approach the opposite. https://www.anandtech.com/show/13255/hot-chips-2018-tachyum-prodigy-cpu-live-blog https://www.anandtech.com/show/13255/hot-chips-2018-tachyum-... I don't think that's the way of the future anyway, but C is not the only programming language, fortunately. Generating the ISA, and then CPU from specification, the next logical step is to generate highly optimized lower-than-C-level code from high-level specifications too.
