What do you mean "hit handling"? Edit: I guess I need a bigger font :-) There's no clock gating; everything gets the clock. There's not a lot to say about HALT

There's no clock gating; everything gets the clock. There's not a lot to say about HALT. It stops memory operations and the prefetch queue, so the processor stops processing until it gets an interrupt.

So ucode is just sitting in that state waiting for Q to fill in for an extra long time is all? Is the prefetch queue flushed or are the next bytes sitting in Q prefetched, simply not presented to ucode?
