| 摘 要： | 研究Java平台的核心--虚拟机.为了使Java在不同的平台上顺利运行,研究Java虚拟机(Java virtual machine,简称JVM)的组成及运行机制,为编程实现JVM或向各种平台移植JVM提供参考.通过对Kaffe(一种Java虚拟机的实现)桌面版本的源代码进行分析,得出虚拟机运行的整个流程,并对流程中的关键部分进行深入研究,同时结合Sun的,总结出实现JVM的一些关键步骤,并提出改进JVM运行效率的建议.

| Abstract: | The Java virtual machine is studied, which is the core of a Java platform. In order that Java can run smoothly on various platforms, the composition and running mechanism of the Java virtual machine are studied and a reference for implementing JVM and porting JVM to other platforms is provided. Through an analysis on the source of Kaffe which shows a case of implementation of the JVM, the flow chart of a running JVM it summarized and in some depth the JVM's key parts are studied. At the same time, some key steps in implementing JVM are summaried and some advices are given which can be used to improve the running efficiency of JVM. |
