| Abstract(in English) | In this paper, we propose Turbo Boost Router, in which an adaptive routing is used when an offered workload is high, while a deterministic routing is used for a lower workload. An adaptive routing typically requires more complicated allocator logic than that of a deterministic routing, resulting in a longer critical path delay. Thus, when we implement both the adaptive routing and deterministic routing in the same router, its maximum operating frequency is limited by the critical path delay of the adaptive routing allocator. In Turbo Boost Router, a higher supply voltage than a normal one is supplied to only the adaptive routing allocator (normal voltage is supplied to the other components) only when an adaptive routing is used so as not to lower the maximum operating frequency compared to the deterministic router. In this paper, the concept of Turbo Boost Router is evaluated with Fujitsu 65nm technology. With a normal workload, 0.8V is supplied to Turbo Boost Router for a deterministic routing, while 1.3V is supplied to the allocator for an adaptive routing when a network congestion is detected. Circuit-level evaluation results show that it can use an adaptive routing without lowering the operating frequency. |
