Cache is a small amount of memory which is a part of the CPU … WebThis unit will look into a memory type known as cache and will discuss how caches improve computer performance. This unit will then discuss the main memory, DRAM (or the Dynamic Random Access Memory), and the associated concept of virtual memory. You will take a look at the common framework for memory hierarchy.

Webmoves data up and down the memory hierarchy, then you can write your application programs so that their data items are stored higher in the hierarchy, where the CPU can … WebThe lower levels of the memory hierarchy tend to be slower, but larger. Thus, a program will achieve greater performance if it uses memory while it is cached in the upper levels of the memory hierarchy and avoids bringing other data into the upper levels of the hierarchy that will displace data that will be used shortly in the future.
WebThe average memory access time (AMAT) can be calculated as AMAT = h×T h+(1−h)×T m. For example, if h = 0.98,T h= 1, and T m= 10, AMAT = 0.98·1+(1−0.98)·10 = 1.18. It is clear that making T hand T mas small as possible, while having h as close to 1 as possible, results in better memory performance. 5.2 Cache WebObvious Solutions to Decrease Miss Rate • Increase cache capacity – Yes, but the larger the cache, the slower the access time – Limitations for first-level (L1) on-chip caches – Solution: Cache hierarchies (even on-chip) – Increasing L2 capacity can be detrimental on multiprocessor systems because of increase in coherence misses
