EnglishIn wireless Network-on-Chip (WiNoC), radio frequency (RF) transceivers account for a significant power consumption, particularly its transmitter, out of its total communication energy. Current WiNoC architectures employ constant maximum transmitting power for communicating radio hubs regardless of physical location of the receiver radio hubs. This paper proposes a closed loop transmitting power control mechanism that, using bit error rate (BER) report obtained at receiver’s side, dynamically calibrates the transmitting power level needed for communication between the source and destination radio hubs to guarantee transmission reliability. Our proposed strategy achieves a significant total system energy reduction by about 40% with an average performance degradation of 3%.
