Cache hit rate = (# hits) / (# hits # misses) = (# hits) / (# accesses). 1 Memory & Cache Memories: Review 2 Memory is required for storing Data Instructions Different memory types Dynamic RAM Static RAM Read-only memory (ROM) Characteristics Access time Price Volatility Cache Memory and Performance Many of the following slides are taken with permission from Complete Powerpoint Lecture Notes for Computer Systems: A Programmer's Perspective (CS:APP) Randal E. Bryant TLC: A Tag-less Cache for reducing dynamic first level Cache Energy Presented by Rohit Reddy Takkala Introduction First level caches are performance critical and are therefore optimized for speed. Modern processors reduce the miss ratio by using set-associative caches and optimize latency by reading all ways in parallel with the TLB(Translation Lookaside Buffer) and tag lookup. 2.
