    Abstract: A system and method for allocating resources receive one or more resource requests describing tasks, each of the one or more resource requests having a request priority, a requested configuration type, and a requestor identifier. In a winner-take-all circuit, all of the existing resource priorities within each configuration of the requested configuration type are compared to determine a highest-priority task occupying each assignment. In a loser-take-all circuit, one or more current highest resource priorities of each configuration within the requested configuration type, which are output from the winner-take-all circuit associated with the requested resource assignment, each of the one or more current resources having a current priority, are compared. One of the one or more current resource configurations within the requested configuration type having the lowest current priority is identified as the lowest-priority current resource configuration. The requested configuration type is allocated to the selected resource request if the request priority is higher than the lowest current priority configuration output from the loser-take-all circuit. The method further comprises continuing to allocate the requested configuration type to the lowest-priority current resource tasks currently occupying the lowest current priority configuration within the requested configuration if the lowest current priority configuration within the requested configuration is higher than or equal to the request priority.

    Abstract: Embodiments of a system and method for providing efficient wideband inverse channelization for direct digital synthesizer based jamming techniques are generally described herein. In some embodiments, metadata associated with a technique for generating a waveform, such as frequency, phase and amplitude parameters, is received. Data select signals and data input are generated based on the received metadata. In-phase and quadrature signals are produced at an output of a first de-multiplexer and a second de-multiplexer, respectively, based on the data select signals and the data input. Frequency modulated signals generated by direct digital synthesizers may be combined in a channel using a separate, distinct channel combiner.
