Modification of the BookSim simulator for modeling networks-on-chip based on two dimensional circulant topologies
Ch. 107. P. 182–192.
In this paper, a review of various high-level models of networks-on-chip, their performance capabilities, and characteristics was carried out. As a result, the BookSim simulator was chosen. Application of circulant topologies for implementation of communication subsystems in networks-on-chip (NoCs) as alternatives to other regular topology was proved. The process of modifying the BookSim simulator described allowed high-level modeling of NoCs with any topologies (including two‑dimensional circulants), as well as testing new routing algorithms in such networks.

High-level simulation is a critical stage for optimizing Network-on-Chip (NoC) design, enabling a reduction in time and resources at subsequent development stages. Existing tools often possess limited configuration flexibility and support a narrow set of traffic models, which complicates the evaluation of networks specialized for specific applications. This paper investigates an approach to extending NoC ...

Networks-on-chip (NoCs) widespread in computing system design are used in many applications. A critical NoC aspect is the interaction between computing cores and in particular the traffic patterns. The relevance of this work stems from the fact that traffic patterns in NoCs are poorly understood and have no general classification; and there are no universal ...

On-chip networks (NoCs) have become a popular choice for designing large multiprocessor architectures. Software-based emulation is often used to perform the design verifcation. However, if the considered design is sufciently large, softwarebased emulation becomes impractically slow. To avoid this limitation, multi-FPGA emulation was introduced, where multiple interconnected FPGAs collectively emulate a single circuit. The number ...

The article discusses routing methods in two-dimensional circulant graphs (each vertex is connected to four neighboring ones). The unique group of symmetries of the circulant graph makes it possible to use it as a topology for high performance computing devices, including networks-on-chip and cluster supercomputers.

This article considers the usage of circulant topologies as a promising deadlock-free topology for networks-on-chip (NoCs). A new high-level model, Newxim, for the exploration of NoCs with any topology is presented.
