论文摘要
本文考虑使用芯片上的无路由网络用作多处理器系统的替代片上互连，要求使用艰苦的实时保证处理处理过程间通信。它提出了一个新颖的分析框架，可以为通过芯片上的无路由网络提供潜伏的上限，并使用该框架来评估此类网络提供实时保证的能力。考虑了无路由网络的不同架构以及基于优先级别的路由器的最先进的虫洞网络，提供了广泛的比较分析。
This paper considers the use of routerless networks-on-chip as an alternative on-chip interconnect for multiprocessor systems requiring hard real-time guarantees for inter-processor communication. It presents a novel analytical framework that can provide latency upper bounds to real-time packet flows sent over routerless networks-on-chip, and it uses that framework to evaluate the ability of such networks to provide real-time guarantees. Extensive comparative analysis is provided, considering different architectures for routerless networks and a state-of-the-art wormhole network based on priority-preemptive routers as a baseline.
