Performance Evaluation of Centralized Reconfigurable Transmitting Power Scheme in Wireless Network-on-chip

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

Description
Summary:Network-on-chip (N°C) is an on-chip communication network that allows parallel communication among all cores to improve inter-core performance. Wireless N°C (WiN°C) 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 N°C platforms. In WiN°C, RF transceivers account for a significant power consumption, particularly its transmitter, out of its total communication energy. This paper evaluates the energy and latency performance of a closed loop power management mechanism which enables transmitting power reconfiguration in WiN°C based on number of erroneous received packets. The scheme achieves significant energy savings with limited performance degradation and insignificant impact on throughput.
