Simulation is one of the main tools used to analyze and test new proposals in the Network-on-Chip field. Several simulators can be found in the literature, among them the Noxim simulator stands out. It is being used by many researchers due to the wireless support and open-source availability. An important issue at the simulation phase is the choice of workload, as it may affect testing the system and its features. The correct workload can lead to rapid and efficient system development, while the wrong one may compromise the entire system evaluation. To ensure a more realistic simulation, simulators usually relies on real workloads by using a trace-driven approach. Although Noxim provides a simple support for input traces, it is very limited to a general behavior of the system, accepting only a generic injection rate parameter over time. Another important part of the simulator is the ability to consider the Processing Elements processing time. We propose in this paper an extension of the Noxim simulator to address these issues. Consequently, results are more realistic and may be possible to predict the total execution time very accurately. This extension is demonstrated and evaluated using the NAS-NPB workload.

Noxim模拟器的跟踪驱动和处理时间延长

仿真是片上网络领域中用于分析和测试新建议的主要工具之一。在文献中可以找到几种模拟器，其中Noxim模拟器最为突出。由于无线支持和开源可用性，许多研究人员正在使用它。在仿真阶段，一个重要的问题是工作负载的选择，因为它可能会影响测试系统及其功能。正确的工作负载可以导致快速有效的系统开发，而错误的工作负载可能会损害整个系统的评估。为了确保更逼真的仿真，仿真器通常通过使用跟踪驱动的方法来依赖实际的工作负载。尽管Noxim为输入轨迹提供了简单的支持，但它非常限于系统的一般行为，随着时间的推移仅接受通用的注入速率参数。模拟器的另一个重要部分是能够考虑处理元素的处理时间。我们在本文中提出了Noxim仿真器的扩展，以解决这些问题。因此，结果更加真实，可能可以非常准确地预测总执行时间。使用NAS-NPB工作负载演示并评估了此扩展。
