Java虚拟机中Java栈以及相关指令的实现

Implement Java Stack and Related Instruction for Java Virtual Machine

Java栈是Java虚拟机中运行时数据区的主要组成部分。大部分虚拟机指令的操作都与Java栈中的框架相关联。该文描述了Java栈在Java虚拟机运行中所起的作用,自行设计了一种Java栈的数据结构,提出了一些具有代表性的字节码指令的实现方法。同时总结了Java栈对虚拟机运行效率的影响。

Java stack is the main c omponent of run time data area in java virtual machine.Most byte code instruc tions' operation is related to the frame of java stack.This article describes the function of java stack when java virtual machine runs and designs a kind of data structure for java stack.The article poses implementations for some typic al instructions.At the same time ,the article summarizes java stack's influe nce on running efficiency of java virtual machine.
