THE STUDY AND REALIZATION OF INSTRUCTION FOLDING IN JAVA PROCESSOR

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

In this paper, the technology of instruction folding in Java processor is studied on the basis of analyzing the Java virtual machine and Java bytecodes. Three folding strategies: two folding, three folding, and four folding are analyzed, compared and realized. The results show that four folding can provide higher performance/spending ratio.
