The processor checks whether a corresponding entry is available in the cache every time it needs to read or write a location, thus reducing the time required to access information from the main memory.
WebUsed for high-speed I/O devices able to transmit information at close to memory speeds. Device controller transfers blocks of data from buffer storage directly to main memory without CPU intervention. Only one interrupt is generated at the beginning and end of each block, rather than at the beginning and end of each word. WebHigh-speed buses operate until the cache is stored. Level 3 cache (L3) or base memory The L3 cache is larger, but L1 and L2 are faster. Size ranging from 1 MB to 8 MB. In multiprocessor processors, each core may have separate L1 and L2, but all cores have a common L3 case. The double speed with L3 RAM. Importance of cache memory
