Cache Tables: Paving the Way for an Adaptive Database Cache

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...

Making the Most of Cache Groups

Cache groups are a powerful concept for database caching, which is used to relieve the backend database load and to keep referenced data close to the application programs at the “edge of the Web”. Such cache groups consist of cache tables containing a subset of the backend database’s data, guided by cache constraints. If certain query types are anticipated in the application workload, specifica...

A Power Aware Cache and Register File Design Space Exploration

Adaptive Mode Control for Low-Power Caches Based on Way-Prediction Accuracy

This paper proposes a novel cache architecture for low power consumption, called “Adaptive Way-Predicting Cache (AWP cache).” The AWP cache has multi-operation modes and dynamically adapts the operation mode based on the accuracy of way-prediction results. A confidence counter for way prediction is implemented to each cache set. In order to analyze the effectiveness of the AWP cache, we perform...
