OOh what's this?
I have a fetch time prediction unit installed! It looks at the current address of the prom +1 and compares it to see if it will be a fast or slow decode time :3
Lookahead on the left, current address on the right:

And look! I'm almost done the main part of the CPU, I have to figure out the optimal timing for my instructions here... but once I figure it out, the cpu will be able to carry out all the main ops

I just have to get going on the branching stage now, I'm putting it in the middle of my prefetch buffer. It's going to be doing some speculative prefetching too :3
