A clean operation makes data from store operations performed by the set of c

A clean operation makes data (from store operation ....) visible to ... at a
point common to both sets. It achieves so by performing a write transfer (o
f ....) to that point, provided/if a coherent agent performed a store operat
ion (which modified data since ........ )

我说的就是这个。ISA开源没屁用。

能从ISA做出有竞争力的IP的玩家从来都是少数，剩下的人还是要从这些少数玩家手里买
IP。

所以ISA收不收钱对于多数玩家而言没什么意义。真正有实力搞出IP的玩家也不差这点儿
授权费。
