Memory coherence

WebCache coherence consumes a LOT on-chip bandwidth. Think about all the messages it will send for a single transation. And this transaction can be easily triggered by normal read/write. So the cache coherent protocol end up using a lot on-chip bandwidth. This is problematic for two reasons: a) the NoC bus/ring is shared. WebBackground. Traditional cache coherence protocols, either directory-based or snooping-based, are transparent to the programmer in the sense that they respect the memory consistency model of the system, and hence there is no e ect on memory ordering due to the coherence protocol. On the other hand, there is an ever larger demand on hardware
