摘要

在本文中,我们提出了一种适用于低功耗高性能架构的全异步NoC的动态电压缩放(DVS)策略。分布式交换机策略是一种FIFO自适应分布式交换机,使用两个FIFO阈值级别进行决策。它明智地调整开关电压之间只有三种电压模式。所介绍的架构在90纳米CMOS技术上进行了精确的Spice模拟。实验结果表明,在饱和率为90%的网络中,与基于链路利用率的分布式交换机策略相比,fifo自适应分布式交换机策略不仅降低了实现成本,而且还节省了31%的能量延迟。

Dynamic voltage scaling for fully asynchronous NoCs using FIFO threshold levels
In this paper, we propose a dynamic voltage scaling (DVS) policy for a fully asynchronous NoC suitable for low-power yet high-performance architectures. The DVS policy is a FIFO-adaptive DVS, which uses two FIFO threshold levels for decision. It judiciously adjusts switch voltage among only three voltage modes. The introduced architecture is simulated in 90nm CMOS technology with accurate Spice simulations. Experimental results show that the FIFO-adaptive DVS not only lowers the implementation cost, but also achieves another 31% energy-delay saving compared to the DVS policy based on link utilization, in a 90% saturated network.
