数据相关性 meaning in English
data dependence
data dependency
Examples
- In both cases we can derive data dependences from reaching definitions and uses information obtained by data flow analysis . at schedule time true register dependencies are known , so register analysis does not involve any complication . but for memory dependencies we have to deal with the problem of aliasing ( addresses are computed during execution )
而对于存储器访问指令而言，其相关性分析则相对复杂得多，关键问题是必须解决存储器访问地址的别名问题( aliasingproblem ) ，即必须判断出对存储器的两次访问是否针对同一个地址单元，然后在此基础上进行存储器访问的数据相关性分析。 - In this thesis , we will review some traditional methods of detecting data dependence and analyze the relation between the data dependence and the mechanism of parallelism . based on path analysis and symbolic execution , we describe two methods , static analysis and dynamic analysis , for detecting data dependence of array variables in loops of sequential programs
进而提出了基于路径分析和符号执行的静态测试和动态测试方法，来研究串行程序中循环内部数组变量的数据相关性，该方法对于下标表达式为线性表达式时有很好的效果，而且能够处理一些复杂的数组下标表达式，比如数组下标表达式含有输入变量和非线性下标表达式的情况。
