| Subject: | [Gems-users] SM/OM state in MOESI protocol |
|
Hi Everyone,
I would like to know why in SM/OM state, if the processor issues a load, it can be considered as hit, and load can use the old copy? Because there should be an outstanding store to the same location before the load, and the load should get the new data, instead of the old copy. In MESI protocol, I noticed that SM cannot service load, which is reasonable. Can anyone help me? Thanks!
Xuehai
