Cpu Design Questions
The cache hit rate in CPU design refers to the percentage of times that a requested piece of data or instruction is found in the cache memory instead of having to be fetched from the main memory. It is a measure of how effectively the cache is able to store and retrieve data. A high cache hit rate indicates that the cache is efficiently storing frequently accessed data, resulting in faster access times and improved overall system performance. Conversely, a low cache hit rate suggests that the cache is not effectively storing frequently accessed data, leading to more frequent accesses to the slower main memory and potentially slower system performance.
