WebCached data works by storing data for re-access in a device’s memory. The data is stored high up in a computer’s memory just below the central processing unit (CPU). It is stored in a few layers, with the primary cache level built into a device’s microprocessor chip, then two more secondary levels that feed the primary level. WebThe effectiveness of cache memory to improve performance is based on the following conditions: Regular memory is located off-chip and has a longer access time than on-chip memory. The largest, performance-critical instruction loop is smaller than the instruction cache. The largest block of performance-critical data is smaller than the data cache.
WebThe performance of the cache memory is frequently measured in terms of a quantity called hit ratio. When the CPU refers to memory and finds the word in cache, it is said to …
