Behavioral-level event-driven power management for DECT digital receivers

Abstract

Power management is a low-power design technique applicable in almost all design levels. Here, the idea of exploiting events to trigger the shut-down of hardware resources is applied at the behavioral-level of a DECT digital receiver design. Power management involves a trade-off between the power savings arising from the power-down (or shut-down) parts of the system and the power increase due to the additional logic for the generation of the shutdown signals. For that purpose, taking into account the digital receiver's characteristics, a behavioral-level power management technique is introduced. The efficiency of the proposed technique is proven by its application on an industrial DECT receiver, where a power saving of 50% in terms of the dynamic power consumption is achieved.
