In some implementations, a method includes analyzing an amount of data communicated by a set of network interfaces. The data communicated by the set of network interfaces is processed by a set of functional units and a set of queues includes the data communicated by the set of network interfaces. The method also includes activating a first functional unit of the set of functional units when a first size of a first queue of the set of queues is above a first threshold. The method further includes deactivating the first functional unit of the set of functional units when the first size of the first queue of the set of queues is below a second threshold. The method further includes causing the data to be forward to one or more active functional units via a data interconnect coupled to the set of network interfaces and the set of functional units.

An apparatus may be provided. The apparatus may comprise a first circuit portion, a second circuit portion, and a third circuit portion. The first circuit portion may comprise a voltage supply having an input voltage level (V) and a first switch. The second circuit portion may comprise a plurality of parallel paths. The third circuit portion may comprise a second switch and a third switch. The plurality of parallel paths may supply a portion of the input voltage level when the first switch is open, the second switch is closed, and the third switch is open.
