Abstract: A method and system of managing calls over a data network (20) includes determining an available bandwidth of the data network (20). After a call request is received for establishing a call between at least two network terminals (14, 16, 30), one or more of a plurality of resource elements are selected in response to the call request based on the bandwidth of the data network (20). The resource elements, which can include codecs (coders/decoders), packet sizes (for carrying audio data), and others, are used in the requested call between the at least two network terminals (14, 16, 30). Further, a plurality of communities (402, 404, 406) may be defined each including one or more terminals. One or more usage threshold values may be assigned to a link or links (430, 432) between communities (402, 404, 406), and a call request is processed based on the one or more usage threshold values. The processing includes at least one of determining whether to admit the call request and selecting resource elements to be used during a call between terminals over the link (430, 432).

Abstract: A fast Fourier transform (FFT) processor is constructed using discrete Fourier transform (DFT) butterfly modules having, in preferred example embodiments, sizes greater than 4. In a first example embodiment, the FFT processor employs size-8 butterflies. In a second example embodiment, the FFT processor employs size-16 butterflies. In addition, low power, fixed coefficient multipliers are employed to perform nontrivial twiddle factor multiplications in each butterfly module. The number of different, nontrivial twiddle factor multipliers is reduced by separating trivial and nontrivial twiddle factors and by taking advantage of twiddle factor symmetries in the complex plane and/or twiddle factor decomposition. In accordance with these and other factors, the present invention permits construction of an FFT processor with minimal power and IC chip surface area consumption.
