In the last few years, microprocessors have included support for cache coherence and interconnecting small numbers of processors (two to four) within the microprocessor die, further reduc-ing the cost of small-scale multiprocessors and …
WebTechnische Universität Dresden — TU Dresden WebJul 18, 2016 · Software cache coherency must carefully time the cleaning and invalidating of caches. Cache cleaning involves writing ‘dirty’ data from local cache out to system memory. And cache invalidation is about removing stale or invalid data from the cache before reading new data from the system memory.
WebThe coherence missescan be broken into two separate sources. The first source is true sharing missesthat arise from the communication of data through the cache coherence mechanism. In an invalidation based protocol, the first write by a processor to a shared cache block causes an invalidation to establish ownership of that block.
