The On-Chip Interconnects (OCI) infrastructure represents one of most important components in determining the overall performance of future System-on-Chip (SoC). Recently, nano-communication has emerged as a new paradigm that allows nanomachines to communicate using mechanisms, such as molecular-based, electromagnetic-based, acoustic-based, and mechanical-based techniques. In this paper, we study and evaluate the performance of the electromagnetic-based communication technique as an on-chip communication fabric for SoCs. Simulations have been conducted and preliminary results are reported to shed more light on the performance of this technique for large SoCs.

Network-on-chip (NoC) has been proposed for SoC (System-on-Chip) as an alternative to on-chip bus-based interconnects to achieve better performance and lower energy consumption. Several approaches have been proposed to deal with NoCs design and can be classified into two main categories, design-time approaches and run-time approaches. Design-time approaches are generally tailored for an application domain or a specific application by providing a customized NoC. All parameters, such as routing and switching schemes, are defined at design time. Run-time approaches, however, provide techniques that allow a NoC to continuously adapt its structure and its behavior (i.e., at runtime). In this paper, performance evaluation of a flow control algorithm for congestion avoidance in NoCs is presented. This algorithm allows NoC elements to dynamically adjust their inflow by using a feedback control-based mechanism. Analytical and simulation results are reported to show the viability of this mechanism for congestion avoidance in NoCs.

Summary In recent years, there has been rapid and significant development of road transport technologies in order to reduce the number of killed and injured people on roads. These include safety technologies, emergency call systems (eCall), and advanced traveler information systems. The eCall system is an automatic in‐vehicle emergency call service, which is mainly used for notifying emergency services about dangerous road situations and their exact location. In this paper, an eCall platform prototype is developed to allow quick and efficient rescue of injured people in dangerous road situations. The eCall function is developed and installed in nomadic devices (e.g., smartphones and tablets). Large‐scale field operational tests were conducted in real settings to assess the impacts of the eCall function provided by in‐vehicle nomadic devices. More precisely, experiments were conducted by more than 250 participants with different sociodemographic profiles in order to study the users' acceptance of the use of the developed eCall function for large‐scale usage. The collected data are analyzed, and results are reported. Performed experiments showed the usefulness, acceptance, and satisfactory performance of the eCall service.

Recent studies have shown that to improve the performance of specific System-on-Chip (SoC) application domain, the OCI (On-Chip Interconnect) architecture must be customized, at design time. These approaches are generally tailored to a specific application, providing an application-specific SoC. They deal with the selection of OCI architecture to accommodate the expected applicationspecific data traffic pattern during early design-space exploration phase. For dynamic SoCs, in which traffic pattern of applications is not known or predictable in advance, an efficient OCI is required. In this paper, we present an approach to allow designers to customize a candidate OCI architecture in order to match large application workload. Simulations results, using 2D mesh, show that this method achieves better performance compared to the basic 2D mesh OCI architecture, while using little resource budget.
