Wireless extension to the existing SystemC design methodology

This research uses a SystemC design methodology to model and design complex wireless communication systems, because in the recent years, the complexity of wireless communication systems has increased and the modelling and design of such systems has become inefficient and challenging. The most important aspect of modelling wireless communication systems is that system design choices may affect the communication behaviour and also communication design choices may impact on the system design. Whilst, the SystemC modelling language shows great promise in the modelling of complex hardware/software systems, it still lacks a standard framework that supports modelling of wireless communication systems (particularly the use of wireless communication channels). SystemC lacks elements and components that can be used to express and simulate wireless systems. It does not support noise links natively. To fill this gap, this research proposes to extend the existing SystemC design methodology to include an efficient simulation of wireless systems. It proposes to achieve this by employing a system-level model of a noisy wireless communication channel, along with a small repertoire of standard components (which of course can be replaced on a per application basis). Finally, to validate our developed methodology, a flocking behaviour system is selected as a demonstration (case study). This is a very complex system modelled based on the developed methodology and partitioned along different parameters. By applying our developed methodology to model this system as a case study, we can prove that incorporating and fixing the wireless channel, wireless protocol, noise or all of these elements early in the design methodology is very advantageous. The modelled system is introduced to simulate the behaviour of the particles (mobile units) that form a mobile ad-hoc communication network. Wireless communication between particles is addressed with two scenarios: the first is created using a wireless channel model to link each pair of particles, which means the wireless communication between particles is addressed using a Point-to-Point (P2P) channel; the other scenario is created using a shared channel (broadcast link). Therefore, incorporating wireless features into existing SystemC design methodology, as done in this research, is a very important task, because by developing SystemC as a design tool to support wireless systems, hardware aspects, software parts and communication can be modelled, refined and validated simultaneously on the same platform, and the design space expanded into a two-dimensional design space comprising system and communication

Modeling of flocking behaviour system in SystemC

This paper introduces the integration of communication modelling into design modelling during the early stages of system development. It presents the modelling of flocking behaviour system in SystemC, which is emerging as a suitable language for designing and modelling. SystemC provides a consistent methodology for the design and refinement of complex digital systems. In this paper, a demonstrator implementing communication between particles has been constructed and incorporated into the entire design methodology. The communication has been implemented through the incorporation of a wireless channel that was previously modelled
