Because loops are usually executed many times , loops optimization is a major aspect in optimal compilation 摘要讨论了循环优化的目标和循环优化的各种程序变换方法。
And then , it gives some useful approaches of program transformation to reduce cache conflicts , and concludes three accessing modes in multi - media applications to prepare for the further study of stream cache prefetching technologies . this paper also introduces a data allocation approach to scratch - pad sram , with the purpose of improving cache hit rate 讨论了常用的提高数据时空局部性的程序变换方法以降低cache失效率,并针对多媒体领域应用程序的特点,总结了三种多媒体常见存储访问模式,为进一步研究并向dpc存储系统加入流cache的预取技术奠定了基础。
