摘　　要：本文提出了一种针对Java卡虚拟机的硬件结构 .Java卡虚拟机是Java语言与智能卡之间的接口 ,开发支持Java语言的智能卡对IC卡的发展十分重要 .现有的智能卡中实现的Java卡虚拟机性能较差 ,本文给出一种基于Java卡虚拟机的专用CPU结构 ,该结构直接执行Java字节码 ,并采用了两条指令合并机制 .文中将详细介绍所提出的硬件结构 ,包括指令集的选取 ,模块划分及各功能模块结构 。The paper proposes a hardware architecture for Java Card Virtual Machine.The Java Card Virtual Machine is the interface between Java language and smart card.It is very important for the development of IC card to exploit smart card supporting Java language.But the performance is poor for the existing smart cards that have realized Java Card Virtual Machine.In this paper a hardware architecture aiming at Java Card Virtual Machine is given which can execute directly the Java bytecodes and has adopted the mechanism of two instruction folding.This paper will introduce the hardware architectures in details,including instruction set selection,module partition and its architecture,and the mechanism of two instruction executing concurrently is emphasized.
