【摘要】 介绍了一种新的代码优化的方法———JustInTimeCodeLayout ,它不同于传统的静态链接生成可执行程序映象文件的方法 ,而是在运行时通过动态链接生成执行程序的映象 ,对比研究了此方法生成的程序映象和传统方法生成的程序映象及用Pettis方法优化生成程序映象三者之间在运行时Cache性能的差异 ,证明了这种方法对程序运行的明显效果。更多还原

【Abstract】 This paper introduces a new method of executable image generation,J ITCL,which is different from traditional method in that it generats the program image by loading module and layout code in run-time.And it compares the cache pe rformance of 3 kinds of image,one of which is not optimized,the other is optimiz ed in Pettis method and the third one is generated in JITCL method. The re sult shows that JITCL is a promising alternative to the Pettis method .更多还原
