I think you meant PLA.

just thought it would be really neat to write a program that's a processor
compiler (like LLVM, but for digital logic) in that you feed in the
definition of the ISA and the ALUs and it automatically generates a
processor including all the pipelines, forwarding, stalling, and other
logic. I was halfway hoping that samuel's code would be that impressive.
