Networks on Chip (NoC) have emerged as the design paradigm for scalable System on Chip (SoC) communication infrastructure. Due to convergence, a growing number of applications are integrated on the same chip. When combined, these applications result in use-cases with different communication requirements. The NoC is configured per use-case and traditionally all running applications are disrupted during use-case transitions, even those continuing operation.In this paper we present a model that enables partial reconfiguration of NoCs and a mapping algorithm that uses the model to map multiple applications onto a NoC with undisrupted Quality-of-Service during reconfiguration. The performance of the methodology is verified by comparison with existing solutions for several SoC designs. We apply the algorithm to a mobile phone SoC with telecom, multimedia and gaming applications, reducing NoC area by more than 17% and power consumption by 50% compared to a state-of-the-art approach.

“…Therefore, heuristics have to be used to find a solution with a reasonable quality within an acceptable time. In [11], a minimal weight algorithm is proposed to map a digital audio broadcast receiver onto a tiled SoC in a reasonable time, where the optimization metric is to minimize the energy consumption. Run-time mapping offers a number of advantages over design-time mapping, especially for a Cognitive Radio which dynamically changes its behavior.…”

Abstract-Cognitive Radio has been proposed as a promising technology to solve today's spectrum scarcity problem. Cognitive Radio is able to sense the spectrum to find the free spectrum, which can be optimally used by Cognitive Radio without causing interference to the licensed user. In the scope of the Adaptive Adhoc Freeband (AAF) project, an emergency network built on top of Cognitive Radio is proposed. New functional requirements and system specifications for Cognitive Radio have to be supported by a reconfigurable architecture. In this paper, we propose a heterogenous reconfigurable System-on-Chip (SoC) architecture to enable the evolution from the traditional software defined radio to Cognitive Radio.
