Abstract

A core mapping method for reconfigurable network-on-chip (NoC) architectures is presented in this paper. In most of the existing methods, mapping is carried out based on the traffic characteristics of a single application. However, several different applications are implemented and integrated in the modern complex system-on-chips which should be considered by mapping methods. In the proposed method, the reconfiguration (which is achieved by embedding programmable switches between routers of a mesh-based NoC) allows us to dynamically change the network topology in order to adapt it with the running application and optimize the power and performance metrics. The presented network architecture can be configured as an application- specific topology, while it still holds the benefits of the regular NoC topologies such as modularity and predictable electrical properties. The experimental results show that this method can effectively adapt the NoC to the running application and improve the power consumption and performance of the system.
可重构NoC架构的功率感知映射
提出了一种可重构片上网络(NoC)体系结构的核心映射方法。在现有的大多数方法中,映射是基于单个应用的流量特征进行的。然而,在现代复杂的片上系统中实现和集成了几种不同的应用,这应该通过映射方法来考虑。在提出的方法中,重构(通过在基于网格的NoC的路由器之间嵌入可编程交换机实现)允许我们动态改变网络拓扑,以适应运行的应用程序并优化功耗和性能指标。所提出的网络体系结构可以配置为特定于应用程序的拓扑,同时它仍然具有常规NoC拓扑的优点,例如模块化和可预测的电气特性。实验结果表明,该方法能有效地使NoC适应运行应用,提高系统功耗和性能。
