When on-chip interconnection network scales to integrate more processing elements, the average end-to-end latency is highly increased due to long average hop distance. Though it has been discovered that, almost of the communication in large scale networks is between nodes in a short range, it revealed that the small portion of data delivery between distant nodes consumes or occupies most of the network...
Many-Core System-on-Chips (MCSoCs) require efficient task migration approach in order to reach system performance objectives such as load balancing, communication optimization, fault tolerance, and temperature control. In this paper an efficient self-aware migration approach is introduced for NoC-based MCSoCs using a centralized feedback controller in order to control the congestion over the system...
This paper investigates the resource allocation problem for the Gaussian multiple access channel (MAC) with conferencing links, where the two transmitters can talk to each other via wired rate-limited channels. Moreover, the two transmitters are powered by a shared energy harvester which captures energy from the environment. We consider both the non-causal (the energy arrival levels at future time...
An overlaid mesh with unequal RF nodes placement has been introduced to improve network performance of wireless network-on-chip benefited from the greatly reduced network diameter. Traffic however can easily get crowded at big RF nodes due to the sharing and competition of multi-channel usage. To alleviate traffic congestion, a load adaptive channel distribution and arbitration scheme is proposed...
In this paper, we investigate the resource allocation schemes in a two-user Gaussian multiple access channel (MAC) with conferencing links and a shared energy harvesting (EH) source to maximize the weighted throughput for the two transmitters over a finite horizon of N time slots. In particular, we adopt a block-based EH model, for which the energy arrive at the beginning of each slot and the amount...
To bridge the widening gap between computation requirements of ubiquitous application and communication efficiency faced by gigascale multi-processor system-on-chip (MP-SoC) devices, a new on-chip communication system, dubbed wireless network-on-chip (WNoC), is proposed by using the recently developed CMOS ultra wideband (UWB) intrachip wireless communication. In this work, we propose a distributed...
