PLA outputs per opcode

Post by RichTW »

I was wondering: is there a document anywhere which breaks down the PLA outputs per opcode per T state? I've only been able to find this, which lists the PLA outputs and the condition which fires them, but that needs a fair bit of processing to turn into a sequence of PLA outputs for each cycle of an opcode.

AFAIK, that wiki page and the links within are the best you'll get, but I'd be interested to know better!

Actually the page itself contains a ruby script to process the PLA entries per opcode - right at the bottom of the page. It is not too complicated to write a small programm doing the same in your favorite language.
