摘要： Systems and techniques are described for applying a polar bias modulation having a phase component and an amplitude component to a signal amplified by a power amplifier. The power amplifier (PA) has a plurality of amplifier gain stages and is configured to amplify an input to create an amplifier output signal. The input to the power amplitude is phase modulated based upon the phase component of the polar bias modulation, but need not be amplitude modulated. Amplitude modulation is provided by logic that includes a detector configured to receive an indication of the amplifier output as a feedback signal, a control module configured to generate a control signal based upon both the feedback signal and the amplitude component of the polar bias modulation, and a bias circuit configured to adjust a bias signal associated with at least one of the plurality of amplifier gain stages in response to the control signal. Such a modulation scheme may be readily applied in enhanced data rate for global service mode (GSM) evolution (EDGE) applications, as well as in other environments that make use of polar modulation.

摘要： Methods and corresponding systems in a Viterbi decoder include selecting an input symbol in an input block, wherein the input block has a plurality of input symbols, wherein each input symbol has a Boolean value, a quality value, and an associated stage, and wherein the selected symbol is selected based upon the quality value of the selected symbol relative to a quality value of other input symbols in the input block. Thereafter, the Boolean value of the selected symbol is complemented to produce a complemented symbol. The complemented symbol is substituted for the selected symbol to produce an alternate input block. A Viterbi algorithm is executed using the alternate input block to produce an alternate decoded bit sequence, which is then checked for errors using an error check. The alternate decoded bit sequence is output in response to the alternate decoded bit sequence passing the error check.

摘要： A technique for performing a discrete Fourier transform (DFT) includes storing, in a single-port memory, multiple signal points. A first group of consecutive ones of the multiple signal points are fetched (from a first line of the single-port memory) to a first input register associated with a processor that includes multiple arithmetic units (AUs) that are each configured to perform multiply accumulate (MAC) operations. A second group of consecutive ones of the multiple signal points are then fetched (from a second line of the single-port memory) to a second input register associated with the processor. Selected pairs of the multiple signal points are then loaded (one from each of the first and second input registers for each pair) into the multiple arithmetic units during an initial butterfly stage. Radix-2 butterfly operations are then performed on the selected pairs of the multiple signal points (using the multiple AUs) to provide respective output elements.

摘要： A coprocessor (14) may be used to perform one or more specialized operations that can be off-loaded from a primary or general purpose processor (12). It is important to allow efficient communication and interfacing between the processor (12) and the coprocessor (14). In one embodiment, a coprocessor (14) generates and provides instructions (200, 220) to an instruction pipe (20) in the processor (12). Because the coprocessor (14) generated instructions are part of the standard instruction set of the processor (12), cache (70) coherency is easy to maintain. Also, circuitry (102) in coprocessor (14) may perform an operation on data while circuitry (106) in coprocessor (14) is concurrently generating processor instructions (200, 220).
