Abstract: Dual mode filters having two reconfigurable multi-stage filters. In a dual band mode, each reconfigurable filter filters an input signal in a different band using every filter stage. In a single band mode, both reconfigurable filters are effectively divided into two sub-chains that include either the odd-numbered filter stages or the even-numbered filter stages. Together, the four sub-chains in the single band mode filter an input signal in a single band with a higher parallelization than each reconfigurable filter in the dual band mode. In some embodiments, the dual mode filter is a decimation filter. In other embodiments, the dual mode filter is a resampling filter. In still other embodiments, the dual mode filter is an interpolation filter.

Abstract: A technique for reinitializing a coupled circuit, the technique including receiving a common configuration value associated with states of a coupled circuit, tracking states associated with the coupled circuit while the coupled circuit is in a low power state based on the common configuration value, receiving the tracked state associated with the coupled circuit, receiving a scaling value associated with the coupled circuit, determining a current state of the coupled circuit based on the tracked state and the scaling value, and transmitting an indication of the current state to the coupled circuit when the coupled circuit has exited the low power state.
