摘要： 支持Javacard技术标准是智能卡的发展方向，目前的Javacard系统大多是采用软件虚拟机的方式来解释执行或者通过just-in-time方式执行Java指令，系统软件平台本身占用了大量的资源，且执行效率不高。解决这些问题的方法就是实现硬件Javacard指令处理器。该文给出了一种基于微码的Javacard指令处理器的FPGA设计和实现，以Javacard CPU为核心搭建Javacard CPU测试平台，并将其集成在一块FPGA上实现。

Abstract: Javacard is the development direction of smart card. Most of the Javacard systems use the software virtual machine to execute Javacard instruction. The system takes up a great deal of hardware resources, and it is unefficient. The resolution is to implement the hardware Javacard instruction processor. This paper describes a design of Javacard hardware processor based on microcode.

Key words: Javacard, CPU, Smartcard
