Run-time transmission power reconfiguration and adaptive packet relocation in wireless network-on-chip

Network-on-chip (NoC) is an on-chip communication network that allows parallel communication between all cores to improve inter-core performance. Wireless NoC (WiNoC) introduces long-range and high bandwidth radio frequency (RF) interconnects that can possibly reduce the multi-hop communication of t...

Shahrizal TK Electrical engineering. Electronics Nuclear engineering Network-on-chip (NoC) is an on-chip communication network that allows parallel communication between all cores to improve inter-core performance. Wireless NoC (WiNoC) introduces long-range and high bandwidth radio frequency (RF) interconnects that can possibly reduce the multi-hop communication of the planar metal interconnects in conventional NoC platforms. In WiNoC, RF transceivers account for a significant power consumption, particularly its transmitter, out of its total communication energy. CurrentWiNoC architectures employ constant maximum transmitting power for communicating radio hubs regardless of physical location of the receiver radio hubs. Besides, high transmission power consumption in WiNoC with constant maximum power suffers from significant energy and load imbalance among RF transceivers which lead to hotspot formation, thus affecting the reliability of the onchip network system. There are two main objectives covered by this thesis. Firstly, this work proposes a reconfigurable transmitting power control scheme that, by using bit error rate (BER) estimation obtained at the receiver’s side, dynamically calibrates the transmitting power level needed for communication between the source and destination radio hubs. The proposed scheme achieves significant total system energy reduction by about 40% with an average performance degradation of 3% and with no impact on throughput. The proposed design utilizes a small fraction of both area and power overheads (about 0.1%) out of total transceiver properties. The proposed technique is generic and can be applied to any WiNoC architecture for improving its energy efficiency with a negligible overhead in terms of silicon area. Secondly, an energyaware adaptive packet relocator scheme has been proposed. Based on transmission energy consumption and predefined energy threshold, packets are routed to adjacent transmitter for communication with receiver radio hub, with an aim to balance energy distribution in WiNoC. The proposed strategy alone achieves total communication energy savings of about 8%. A joint scheme of the reconfigurable transmitting power management and energy-aware adaptive packet relocator is also introduced. The scheme consistently results in an energy savings of 30% with minimal performance degradation. 2016-06 Thesis http://eprints.utm.my/id/eprint/60717/ http://eprints.utm.my/id/eprint/60717/1/MohdShahrizalRusliPFKE2016.pdf application/pdf en public http://dms.library.utm.my:8080/vital/access/manager/Repository/vital:94079 phd doctoral Universiti Teknologi Malaysia, Faculty of Electrical Engineering Faculty of Electrical Engineering
