Subject: | [Gems-users] L1,L2 state change |
When running in a CMP configuration. Is it possible to use a single controller for both L1 and L2 ? The reason I require this, is that in my protocol, I require to make a state change for a cache block in the L1 and the L2 appear atomic without any intervening memory operations. Hence I need one machine to change state of both L1 and L2, and make it happen instantaneously. The L2 is shared in my configuration. Are there any alternative solutions to this ? I wouldnt want to use a schedule_event on the L2's in port since another memory operation could arrive at the same instant and these two could get reordered in the global event queue.
