Cycle-Accurate Network on Chip Simulation with Noxim
本文介绍了Noxim，一个基于SystemC的开源、可配置、可扩展的周期精确片上网络仿真器，用于分析传统有线NoC和新兴无线WiNoC架构的性能与功耗。
The on-chip communication in current Chip-MultiProcessors (CMP) and MultiProcessor-SoC (MPSoC) is mainly based on the Network-on-Chip (NoC) design paradigm. Unfortunately, it is foreseen that conventional NoC architectures cannot sustain the performance, power, and reliability requirements demanded by the next generation of manycore architectures. Recently, emerging on-chip communication technologies, like wireless Networks-on-Chip (WiNoCs), have been proposed as candidate solutions for addressing the scalability limitations of conventional multi-hop NoC architectures. In a WiNoC, a subset of network nodes are equipped with a wireless interface which allows them long-range communication in a single hop. Assessing the performance and power figures of NoC and WiNoC architectures requires the availability of simulation tools that are often limited on modeling specific network configurations. This article presents Noxim, an open, configurable, extendible, cycle-accurate NoC simulator developed in SystemC, which allows to analyze the performance and power figures of both conventional wired NoC and emerging WiNoC architectures.
