73fd3fe040 Finally fixed the lru bug. It was actually a flush bug all along. At the end of flush writeback FlushAdr is incremented so clearly the dirty bit then clears the wrong set. Must either take an additional cycle to clear dirty and then change the address or clear the dirty bit before the cache bus acknowledgment. Changed it to clear at begining of that line's writeback before actually writting back. 2022-12-17 23:47:49 -06:00

cdeccd78e6 At long last found the subtle bug in the LRU.
Since the LRU memory is two ports, 1 read and 1 write, a write in cycle 1 to address x should not
forward data to a read from address y in cycle 2.
A read form address x in cycle 2 would still require forwarding.
