基于片上网络功率控制的流量管理

Network Traffic Regulation for Networks-on-Chip Power Control

对片上网络中降低功耗的技术进行研究,针对其使用电源门控技术后出现过多次数通电断电次数的缺点,提出时间集中的流量控制方法。利用局部缓存器以及全局控制器对流量进行缓存和集中管理,从而让片上网络中流量在时间上集中,结合电源门控技术使路由器的通电时间最短,达到降低功率损耗的目的。与其他相关技术进行实验比较,实验表明提出的方法能够减少更多的功率损耗。

Studies the technology of reducing power consumption the Networks-on-Chip, and proposes a time-concentrated flow control method for the disadvantages of the number of times of power-off and power-off after using the power-gating technology. The local buffer and the glob. al controller are used to cache and centrally manage the traffic, so that the traffic in the on-chip network is concentrated in time, and the power gating technology is combined to minimize the power-on time of the router, thereby reducing the power loss. Experimental compari. son with other related technologies shows that the proposed method can greatly reduce more power consumption.
