A method and a cache memory controller for fetching data against a central processing unit (CPU) to further reduce CPU idle time

摘要

A method and cache memory controller for fetching data against a CPU to further reduce CPU idle time are disclosed.;Although the cache memory initiated by the conventional cache miss is still in progress and the data word is stored in a memory location corresponding to the memory block offset of the memory block frame to which the data word is mapped, Fetch data from the cache-main memory layer to return to the CPU.;As a result, the CPU idle time due to the cache read miss is further reduced.
