Hi,
We have been working in the MOESI_CMP_directory
protocol and we have seen that when a L1 cache is in
the Owned state and wants to modify the block then it
goes to the Modified state and the other sharers are
invalidated.
We think that the Owned state was used for avoiding
invalidations in the other sharers, by broadcasting
every change that makes. If it has to invalidate then
is the same as another sharer and the owned state is
not necessary, isn't it?
Thank you
/Marco and Enric
