There used to be two primary methods to optimize program data locality: the first is to analyze cache behavior of program data, then basing on cache behavior model, build a program analysis tool which shows the bottlenecks of data cache performance and hence directs programmer to tune performance of data cache; the second is program transformation by an optimizing compiler or an optimizing tool, and data cache performance is optimized in the transformation.

过去在这方面的工作有两个重要的思路：一是针对程序运行时的访问数据，利用相关的Cache行为模型，建立一些程序分析工具，从源代码级给出程序Cache性能的瓶颈，指导程序员通过程序变换来优化程序的局部性，从而提高Cache性能；二是在编译器上开发编译优化过程，或者开发专门的程序优化工具，通过对程序进行分析，在此基础上自动进行程序变换，包括代码变换和数据变换两种，优化程序的局部性，从而提高 Cache性能。
