说明：  针对复杂的传统Java智能卡指令解析问题,结合Applet的部署特点,提出了指令预解析的概念 给出了转换后的Applet文件(CAP,Converted Applet file)中导入组件、常数池和导出组件的预解析优化存储结构及包注册表结构,使用定长存储结构替代原有的变长存储结构以加快查找过程,引入了导出组件辅助索引表以加快外包类的解析过程 设计了基于优化后组件的静态域、静态方法和类访问字节码指令的快速解析流程,将解析算法的时间复杂度降为常数阶 在Applet下载过程中通过预解析来生成优化后的组件存储结构,在执行过程中依据快速解析流程来完成静态域、静态方法和类对象的快速访问,从而缩短了Applet运行时的解析时间.测试结果表明,在不改变标准Applet下载、运行流程的情况下,该方法有效地减少了卡内存储器的访问次数,缩短了解析算法的执行时间,提高了Applet执行的整体性能.

使用java自带的包获取系统数据，容易找不到包，尤其是内存信息不够准确，所以选择使用sigar获取系统信息。  下载地址：http://sourceforge.net/projects/sigar/files/latest/download?source=files     解压压缩包，将lib下sigar.jar导入eclipse的CLASSPATH中，再将sigar-x86-winnt.dll存入Java的bin目录即可。
