Cache Miss vs Cache Hit: What
WebThe miss ratio is the fraction of accesses which are a miss. It holds that. miss rate = 1 − hit rate. The (hit/miss) latency (AKA access time) is the time it takes to fetch the data in case of a hit/miss. If the access was a hit - this time is rather short … WebSome terminologies of page fault are as follows: 1. Page Hit. When the CPU attempts to obtain a needed page from main memory and the page exists in main memory (RAM), it is referred to as a "PAGE HIT". 2. Page Miss. If the needed page has not existed in the main memory (RAM), it is known as "PAGE MISS". 3. WebThe percentage of accesses that result in cache hits is known as the hit rate or hit ratio of the cache. The alternative situation, when the cache is checked and found not to contain any entry with the desired tag, is known as a cache miss. This requires a more expensive access of data from the backing store. ... A memory management unit ... boinmall
