| 中文摘要: |
| 在支持电压岛的片上网络体系结构中,考虑供应电压对数据重传的影响,提出了一种新的能耗模型,并提出了基于电压岛划分、IP核映射和路由算法设计的架构方法．该方法针对电压岛划分、IP核映射和路由算法设计等问题,不仅考虑了IP核的计算能耗,还考虑了IP核之间数据在重传下的数据通信能耗问题．实验结果表明,在考虑数据重传的情况下,该设计方法能有效地降低系统能耗． |
| 英文摘要: |
| For network on chip architecture that supports voltage-frequency islands, a novel energy consumption model and a framework of voltage-frequency islands partitioning, IP mapping and design of routing algorithms considering the impact of the supply voltage on ARQ (automatic repeat request) are presented. This proposed design method considers not only computing energy consumption, but also data communication energy consumption for the voltage-frequency islands partitioning, IP mapping and design of routing algorithms. Experimental results show that the proposed design method can reduce the NoC system energy consumption under ARQ. |
