Sorry if I implied that you may have been working on an HDL CCPU. My
fault, I misinterpreted other peoples posts.

VHDL has a very similar syntax to C, constructs like "if then else"
describe "nano second" hardware rather than stepping through slow
sequential instructions.
Events trigger processes and you can describe as many processes as you
need. It's like parallel computing but at assembler level.
and of it goes.. done.

CCPU carry flag does a few strange things so some work needed to
document the hardware.
