文中在分析Ｊａｖａ 虚拟机及字节码特性基础上，研究了Ｊａｖａ 处理器中的指令合并技术．对３ 种合并策略：２条指令的合并、３ 条指令的合并及４ 条指令的合并进行了分析比较，并分别实现了这３ 种合并策略．研究表明４ 条指令合并策略具有较高的性能／开销比
Based on the analysis of Java virtual machine and bytecode features, this paper studies the instruction merge technology in Java processor. The paper analyzes and compares the three merging strategies: the merging of two directives, the merging of three directives and the merging of the four directives, and respectively implements the three merging strategies. Research shows that the four instruction merge strategies have a higher performance / cost ratio
