Reduction in Cache Memory Power Consumption based on Replacement Quantity

reduction in cache memory power consumption based on replacement quantity

today power consumption is considered to be one of the important issues. therefore, its reduction plays a considerable role in developing systems. previous studies have shown that approximately 50% of total power consumption is used in cache memories. there is a direct relationship between power consumption and replacement quantity made in cache. the less the number of replacements is, the less...

Non-Volatile Memory Based Cache Replacement Policy

Currently, most computer systems consist of Dynamic RAM (DRAM) as main memory and Hard Disk Drives (HDDs) as storage devices. Due to DRAM’s volatile nature, it suffers from data loss in the event of power failure or system crash. With rapid development of new types of non-volatile memory, it becomes promising that one of these technologies will replace DRAM as main memory in the near future. Co...

CMP L2 NUCA Cache Power Consumption Reduction Technique

We analyze how applications use banks in a large shared CMP L2 D-NUCA cache depending on their locality and we define a power consumption model. Then we develop a mechanism to dynamically turn on and off a bankcluster in order to reduce the energy consumption. 1. CMP Way Adaptable Our system is a large shared L2 D-NUCA cache in CMP environment (Figure 1). In this architecture each bank is acces...

Cache Replacement with Memory Allocation

Design of Cache Memory Cell for Leakage Power Reduction

Abstract— This paper represents a successful comparison of 5T cell with 6T cell. Leakage power of conventional 6T cell at 0.18 μm technology has been calculated and is found to be 37.32 pW. Same technology has been implemented on the 5T cell , by which leakage power has been reduced by 37.59%.Various leakage reduction techniques such as Autobackgate Controlled Multi-threshold CMOS (ABC-MTCMOS),...
