Adaptive Replacement Cache

Abstract :

We consider the problem of cache management in a demand paging scenario with uniform page sizes. We propose a new cache management policy, namely, Adaptive Replacement Cache (ARC) that has several advantages. In response to evolving and changing access patterns, ARC dynamically, adaptively, and continually balances between the recency and frequency components in an online and self tuning fashion. The ARC uses a learning rule to adaptively and continually revise its assumptions about the w ....etc

Introduction

Object oriented programming has been the dominant programming paradigm for more than a decade.

OOP languages provide a rich set of features that provides significant software engineering benefits.

The increased productivity provided by these features comes at a justifiable cost of complexity in the runtime environment ,which actually leads to reduced performance and increased energy consumption of programs.

A modern storage hierarchy combines random-access memory, magnetic disk, and possibly optical disk or magnetic tape to try to keep pace with rapid advances in processor performance. I/O devices such as disks and tapes are considered reliable places to store persistent data such as user files. However, random-access memory is viewed as an unreliable place to store persistent data because it is vulnerable to power outages and operating system crashes .Memory's vulnerability to power outages is straightforward to understand and fix. A $100 uninter ....etc

ABSTRACT
A novel approach for estimating articulated body posture and motion from monocular video sequences is pro-posed. Human pose is defined as the instantaneous two dimensional configuration (i.e., the projection onto the image plane) of a single articulated body in terms of the position of a predetermined set of joints. First, statistical segmentation of the human bodies from the background is performed and low-level visual features are found given the segmented body shape. The goal is to be able to map these, g ....etc

The memory hierarchy of high performance and embedded processors has been shown to be one of the major energy consumers. Extrapolating the current trends, this portion is likely to be increased in the near future. In this paper, a technique is proposed which uses an additional mini cache, called the L0-cache, located between the I-cache and the CPU core. This mechanism can provide the instruction stream to the data path, and when managed properly, it can efficiently eliminate the need for high utilization of the more expensive I-cache.
