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. Educational objectives The MESI protocol simulator is widely used in several courses about Computer Architecture, Computer Design and Multiprocessor Systems in the University of Cordoba. The syllab How Does Your Memory Work? Video Questions. 1. What part of your brain springs to action when your memory “network” is activated? . 2. Describe these 3 major functions of memory as described in the video: . Recovered memories. : Memories, . typically of traumatic experiences . that have been forgotten to be retrieved later.. Loftus. : No such thing as recovered memories.. Current thinking. : Some recovered memories are real, but many may be false.. The basic objective of a computer system is to increase the speed of computation. Likewise, the basic objective of a memory system is to provide fast, uninterrupted access by the processor to the memory such that, the processor can operate at its expected speed. .
