Jan 26, 2013 · Cache memory is a small, fast memory located between the CPU and main memory. It stores copies of frequently used instructions and data to accelerate access and improve performance. There are different mapping techniques for cache including direct mapping, associative mapping, and set associative mapping.
Mar 18, 2016 · Memory is organized in a hierarchy with different levels providing trade-offs between speed and cost. - Cache memory sits between the CPU and main memory for fastest access. - Main memory (RAM) is where active programs and data reside and is faster than auxiliary memory but more expensive.
Sep 17, 2017 · Cache memory is a small, fast memory located close to the processor that stores frequently accessed data from main memory. When the processor requests data, the cache is checked first. If the data is present, there is a cache hit and the data is accessed quickly from the cache.
Microsoft PowerPoint - Lec14-cache. 361 Computer Architecture Lecture 14: Cache Memory. cache.1. The Motivation for Caches. Memory System. ° Motivation: Large memories (DRAM) are slow. Small memories (SRAM) are fast. ° Make the average access time small by: • Servicing most accesses from a small, fast memory.
•CPU requests contents of memory location •Check cache for this data •If present, get from cache (fast) •If not present, read required block from main memory to cache •Then deliver from cache to CPU •Cache includes tags to identify which block of main memory is in each cache slot
Cache memory is fast memory that is used to hold the most recently accessed data in slower main memory. The idea is that frequently accessed data will stay in cache, which allows the CPU to access it more quickly, which means it doesn't have to wait for the data to arrive.
Cache Memory Principles Cache memory is intended to give memory speed approaching of the fastest memory available, and at the same time provide a larger memory size at the price of less expensive types of semiconductors memories.
