64位虚拟机SPANVM的设计与实现

Design and Implementation of a 64-Bit Virtual Machine SPANVM

跨平台软件开发和多语言程序设计是当前软件开发中的两个难题,SPANVM是一个基于寄存器和堆栈混合模型的64位运行时系统,凡是符合SPANVM规范的可执行字节码文件都能在移植了该虚拟机的平台上执行。本文介绍了如何设计一个实用的虚拟机系统,包括SPANVM的内存模型、处理器设计、I/O机制和运行时过程,并以SPANVM为基础探讨了跨平台和多语言程序设计的解决方法。

Spanvm is a 64-bit runtime system based on registers and stacks,and is an environment for programs to execute in.It provides all the things needed to run a program. It can execute all bytecode files according to the Spanvm specification.We also introduce how to design a practical virtual machine system,including SPANVM′s memory model,processer design,I/O and runtime process, and put forward a scheme to resolve multi-OS and multi-language programing.
