Cache

Cache. Here we focus on cache improvements to support at least 1 instruction fetch and at least 1 data access per cycle With a superscalar, we might need to accommodate more than 1 per cycle. Typical server and m obile device memory hierarchy c onfiguration with b asic sizes and

The Memory System: Memory Hierarchy

The Memory System: Memory Hierarchy. A Memory System is normally comprised of a hierarchy of memories: Cache - very fast (1 or 2 cycle access), but small (e.g. 32 KB-64 KB) built with SRAM on-board the processor chip
