Cache命中率在现代处理器研究中越来越重要,本文以二维数组为例探讨存储结构Cache命中率的影响.并提出二维数组的以块为主序的存储结构,这种存储结构能较好地保持数据的空间局部性,从而减少了由于数据的空间局部性的破坏而引起的性能的损失. Cache hit rate is more and more important in the modern processor research, this paper takes the two-dimensional array as an example to discuss the impact of cache hit rate of storage architecture.And put forward a two-dimensional array of block-based storage structure, this storage structure can be more Goodly maintain the spatial locality of the data, thereby reducing the loss of performance due to the destruction of spatial data.
