| 摘 要： | 提出一个灵活多核处理器结构:FTPA.首先,通过将单个超块独立映射到单个物理核,FTPA有效减少了超块执行时指令间通信开销.其次,通过将物理核资源划分为需要频繁调整的计算资源和不经常重构的共享资源分别管理,FTPA有效降低了逻辑核的重构开销.最后,通过将计算资源在逻辑上组织成环形拓扑,FTPA实现了逻辑核的任意粒度调整,提供高度的灵活性.运行SPEC2K测试程序的结果显示,FTPA比已有的灵活多核结构TFlex性能平均提升19.2%.

| Abstract: | Nowadays, most chip multiprocessor (CMP) designs face the challenge of how to keep the balance between on-chip parallelism, communication overhead, program performance, and resource utilization. By using the conception of physical core and logical processor, flexible-core CMPs(FCMPs) provide more optimization space. We propose a novel FCMP architecture named FTPA (flexible tiled processor architecture), which provides an efficient platform for single thread execution. The evaluation demonstrates that FTPA outperforms the state-of-art FCMP design, TFlex, by 19.2% on average. |
