This article describes how actual trends of networks-on-chip research and known approaches to their modeling are considered. The characteristics of analytic and high- / low- level simulation are given. The programming language SystemC as an alternative solution to create models of networks-on-chip is proposed, and SystemC models speed increase methodic is observed. The methods of improving SystemC models are formulated. There has been shown how SystemC language can reduce the disadvantages and maximize the advantages of high-level and low-level approaches. To achieve this, the comparison of results for high-level, low-level and SystemC NoC simulation is given on the example of “hot spots” and the geometric shape of regular NoC topologies effect on their productivity.

Network Router

In this paper, we present a novel router architecture for implementing a Reconfigurable Network-on-Chip (RNoC) at high-level design using SystemC. The RNoC is an adaptive NoC-based system-on-chip providing a dynamic reconfigurable communication mechanism. By adding a virtual port – named Routing Modification port – into the conventional router architecture, the network router is able to route communication data flexibly whenever the target routing path is blocked, by unwanted defects or intently by a software programme to meet the requirements of applications. The proposed architecture has been modeled in SystemC/C++, simulated and verified within a 2D mesh 5×5 network platform. In normal communication mode, the static XY routing algorithm is used while the West-First algorithm with a proposed prohibited router surrounding technique is applied in reconfiguration mode. Experimental results are also reported to compare the performance of the network architecture in different operation modes as well as with other works.

An integrated polymer-based magnetohydrodynamic (MHD) pump that can actuate saline fluids in closed-channel devices is presented. MHD pumps are attractive for lab-on-chip applications, due to their ability to provide high propulsive force without any moving parts. Unlike other MHD devices, a high level of integration is demonstrated by incorporating both laser-induced graphene (LIG) electrodes as well as a NdFeB magnetic-flux source in the NdFeB-polydimethylsiloxane permanent magnetic composite substrate. The effects of transferring the LIG film from polyimide to the magnetic composite substrate were studied. Operation of the integrated magneto hydrodynamic pump without disruptive bubbles was achieved. In the studied case, the pump produces a flow rate of 28.1 µL/min. while consuming ~1 mW power.

Due to the complex timing sequence of NAND flash, a unified design process is urgently required to guarantee the reliability of storage system of nano-satellite. Unified Modeling Language (UML) is a widely used high level modeling language for object-oriented design. This paper adopts the UML as the design and modelling tool in the low level storage system design to elaborate the UML application in each phase of design in detail. The result shows taking UML as the modelling tool results in a clear and unambiguity design, which promotes the reliability and quality of software. At last, the feasibility of object-oriented implementation in C is presented.
