A Primer on Memory Consistency and Cache Coherence: Guide …
In computer architecture, cache coherence is the uniformity of shared resource data that ends up stored in multiple local caches. When clients in a system maintain caches of a common memory resource, problems may arise with incoherent data, which is particularly the case with CPUs in a … Meer weergeven In a shared memory multiprocessor system with a separate cache memory for each processor, it is possible to have many copies of shared data: one copy in the main memory and one in the local cache of each … Meer weergeven Coherence defines the behavior of reads and writes to a single address location. One type of data occurring simultaneously in different … Meer weergeven Coherence protocols apply cache coherence in multiprocessor systems. The intention is that two clients must never see different values for the same shared data. The protocol must implement the basic requirements for coherence. It can be tailor-made … Meer weergeven The two most common mechanisms of ensuring coherency are snooping and directory-based, each having their own benefits and drawbacks.
