群集体系结构是将传统的整体寄存器文件分区分为几个较小的寄存器文件，是未来高性能处理器体系结构的候选者之一。积极的分区可以减少寄存器文件的访问时间。另一方面，由于寄存器文件之间的通信，分区使每个时钟周期的说明损失。不仅分区的程度，而且分区寄存器文件的组织还可以支持寄存器文件的访问时间和PE Inter-PE通信的数量。在本文中，我们研究了各种8条问题集群体系结构中适当的分区和分区寄存器文件的组织。结果表明，具有非一致的注册文件组织的八个单发出PE或四个双发PES可以每秒实现最高指令，而与非分区的组织相比，MediaBench Suite的速度为1.59和1.69在Spec2000int套件中。
The clustered architecture, where the conventional monolithic register file is partitioned into several smaller register files, is one of the candidates for the future high performance processor architectures. The aggressive partitioning can reduce the access time of the register file. On the other hand, the partitioning makes losses of instructions per clock cycle due to communication among register files. Not only the degree of partitioning, but the organization of partitioned register files also aects the access time of register files and the amount of inter-PE communication. In this paper, we investigate appropriate degrees of partitioning and organizations of partitioned register files in various 8-way issue clustered architectures. The results show that the eight single-issue PEs or the four double-issue PEs with the non-consistent register file organization can achieve the highest instructions per second and the speedup compared with the non-partitioned organization is 1.59 in the MediaBench suite and 1.69 in the SPEC2000int suite.
