摘　　要：以提高JCVM解释器的执行效率为出发点,以减少解释器工作时对外部存储器的访问次数为目标,提出一种基于双缓冲区的内存调度机制,并给出算法实现的关键片段。分析这种机制存在的不足;与传统方式相比,减少了对内存的访问次数,提高了指令解释执行的连续性程度,提高了解释器执行的效率,简化了系统结构设计的复杂性。Taking the improvement of execution efficiency of Java card virtual machine （JCVM） interpreter as the starting point, and the decrease in times the interpreter accessing the external memory when working as the goal, in this paper we present a double buffer-based memory scheduling mechanism together with the key fragment of implementing the algorithm, as well as analyse the shortages of it ; Compared with conventional means, it reduces the times of memory access, raises the consecutive extent of the instructions＇ interpretation and execu- tion, and it also improves the efficiency of the interoreter execution, simolifies the comnlexitv of svstem structure design.
