| 摘 要： | 不同的层面的程序代码,可以有不同的模块组合方式,把各个模块平均运行次数与模块平均运行时间的卷积做得尽量小是优化的目标,这在数学上是一项复杂的工作。本文通过减少上下文依赖关系,分析静态变量、数据的组织和消除除法等方面探讨了代码的优化。

| Abstract: | We can have different combinations of modules for the code at different levels. To make the average numbers of running various modules and module average running time of convolution as small as possible is the goal of optimization. This is a complex mathematical work. This talks about the optimization of code from the aspects of reducing dependence context, static variables, data organization and elimination division. |
