【Abstract】 This paper introduces a new method of executable image generation JITCL, which is different from traditional method in that it generates the rogram image by loading module and layout code in run-time. And it compares the cache performance of 3 kinds of image, one that is not optimized, one that is optimized by in Pettis method and one that is generated in JITCL method. The results show that JlTCL is a promising alternative to the Pettis method.更多还原
