Abstract: An apparatus to determine a transform of a block of encoded data the block of encoded data comprising a plurality of data elements. An input register is configured to receive a predetermined quantity of data elements. At least one butterfly processor is coupled to the input register and is configured to perform at least one mathematical operation on selected pairs of data elements to produce an output of processed data elements. At least one intermediate register is coupled to the butterfly processor and configured to temporarily store the processed data. A feedback loop is coupled to the intermediate register and the butterfly processor, and where if enabled, is configured to transfer a first portion of processed data elements to the appropriate butterfly processor to perform additional mathematical operations and where if disabled, is configured to transfer a second portion of processed data elements to at least one holding register.

Abstract: An apparatus and method of serializing frequency based image data in a digital cinema system is described. At least one group of data that may be represented as a 16X16 block of data is compiled. Alternatively, a frame of data is compiled. The group of data is divided into four groups, each which may be represented as an 8X8 blocks. Each of the four 8X8 blocks of data are serialized using zig-zag scanning vertical scanning, and/or horizontal scanning.

Abstract: In a remote unit receiver capable of demodulating a plurality of signal instances corresponding to a singe remote unit transmitted signal, a first instance of a signal is demodulated to produce a first set of energy values corresponding to a set of possible data values of the signal. A second instance of the signal is demodulated to produce a second set of energy values corresponding to the set of possible data values. The first and the second sets of energy values are then combined to determine a combined set of energy values. A first estimate of a most likely transmitted data value is determined based upon the combined set of energy values.

Abstract: A Wireless Code Division Multiple Access method and apparatus for determining the transmitted rate of a voice/data signal from a mobile station to a Base Station. Variable rate vocoders transmit voice at one of several predetermined frame rates. The receiver determines the transmitted rate based on one of several frame parameters. One of the parameters is received frame energy. The received frame energy is measured over the length of the relevant portion of the frame. Energy is measured over the half of the frame that can only contain energy if a full rate frame is sent. If the energy measured exceeds a threshold, then full rate is indicated. Else, energy is measured over the fourth of a frame that can only contain energy if a half rate frame is sent. If the energy exceeds a threshold, then half rate is indicated. The procedure is repeated for quarter and eighth rates.
