I was thinking of stack machines when I asked about LLVM in hardware. It is interesting to see them mentioned here. At the end of the second link to the conveyer belt description, it calls the belt a programming model. So is this actually implemented anywhere in conventional hardware. The belt and the way registers are used makes intuitive sense to me. I do not understand exactly where the ALU sits or how flags and interrupts fit in.
I get rather confused going from the basics of Ben Eater/Melvino's 8-bit processor to pipelines and out of order execution. This makes more sense in my surface understanding so far. Thanks for sharing.
