Power modeling of a noc based design for high speed telecommunication systems

Considering the complexity of the future 4G telecommunication systems, power consumption management becomes a major challenge for the designers, particularly for base-band modem functionalities. System level low-power policies which optimize dynamically the consumption, achieve major power savings compared to low level optimisations (e.g gated clock or transistor optimisation). We present an innovative power modeling methodology of a 4G modem which allows to accurately qualify such low power solutions. Then, we show the energy savings attended by these power management methods considering silicium technology.
