Quantifying the Energy Consumption of a Pocket Computer and a Java Virtual Machine

In paper, examine energy consumption of a state- of-the-art pocket computer. Using a acquisition measure energy consumption Itsy Pocket Computer, developed Compaq Computer Corporation's Research Labs. begin byshowing that energy usage characteristics Itsy differ markedly notebook computer. Then, expect flexible software environments become increasingly valent pocket computers, consider applications Javaenvironment. particular, explain some of Java design tradeoffs applicable to pocket computers, quantify energy costs. design options considered the three workloads studied, find a maximum change energy 25%. 1. INTRODUCTION Advances battery technology low-power circuit cannot, themselves, energy demands computers 2]. Thus, critical software running these devices designed minimize energy consumption. However, designing energy-efficient software requires the software developer understand energy- usage characteristics computer which software run energy impact software design cisions. In pap..
