Abstract: Embodiments disclosed herein relate to reducing power consumption of an electronic device scanning for wireless communication signals while maintaining or even improving an efficiency of the scanning operations. To do so, the electronic device may include more than one scan core, such as a main core and a receiving core. The receiving core may have limited functionality compared to the main core. For example, the receiving core may only receive wireless signals (including scanning for wireless signals). That is, the receiving core may not support certain operations that consume relative high power that are supported by the main core, such as transmission of signals. In this way, operation of the receiving core, either in place of or in addition to the main core, may reduce power consumption of the electronic device by avoiding high power consuming operations, such as data transmission, while scanning for various signals.
