一种多核系统中的二维块数据存储机制

摘要

针对多核系统中处理二维数据时的数据对齐、地址映射等问题,提出一种多核系统中的二维块数据存储机制.介绍二维块数据在计算前后的数据分配、寻址及传输机制及一般应用方法,并对典型应用进行仿真验证.结果证明,该存储机制能减轻处理单元和存储单元间的不平衡性,改善一维和二维之间的不匹配现象.%To solves some common problems in 2D data processing such as data alignment and address mapping, this paper presents the mechanism of 2D block data access in multi-core system. It introduces the principle of data mapping, addressing, and data transmission. It applies a general method. Simulation result proves that the mechanism can increase the efficiency of data access and decrease the imbalance between 1D and 2D.
