In this paper, we propose SVR-NoC, a network-on-chip (NoC) latency model using support vector regression (SVR). More specifically, based on the application communication information and the NoC routing algorithm, the channel and source queue waiting times are first estimated using an analytical queuing model with two equivalent queues. To improve the prediction accuracy, the queuing theory-based delay...
During the last decade, we have witnessed a major transition from computation- to communication-centric design of integrated circuits and systems. In particular, the network-on-chip (NoC) approach has emerged as the major design paradigm for multicore systems-on-chip (SoC). The major challenges in traditional wire-based NoCs are the high latency and power consumption of the multi-hop links. By inserting...
In this work, we propose a new, accurate, and comprehensive analytical model for Network-on-Chip (NoC) performance analysis. Given the application communication graph, the NoC architecture, and the routing algorithm, the proposed framework analyzes the links dependency and then determines the ordering of queuing analysis for performance modeling. The channel waiting times in the links are estimated...
In recent years, multiple Voltage Frequency Island (VFI)-based designs have increasingly made their way into both commercial and research multicore platforms. On the other hand, the wireless Network-on-Chip (WiNoC) architecture has emerged as an energy-efficient and high bandwidth communication backbone for massively integrated multicore platforms. It becomes therefore possible to exploit the small-world...
