摘要： A logic circuit latch including an input stage for receiving a logical input signal and a pair of differential amplifiers, each having an input operatively coupled to the input stage, and at least one of them having an output arranged to supply the logical output of the latch. Each of the differential amplifiers includes a transistor connected as a load, and an output of each of the differential amplifiers is coupled to bias the load transistor of the other differential amplifier. If the latch switches from the transparent state to the closed state while the logical input signal is transitioning between logical levels, the differential amplifiers drive up the logical output of the latch if the logical input signal transitions from a first to a second logical level, and drive down the logical output of the latch if the input signal transitions from the second to the first logical level.

摘要： A computer system has a processor that has a prediction array that avoids conflicts when the prediction array is accessed twice in once clock cycle to retrieve predictions for two separate conditional branch instructions. The prediction array is included as part of a branch prediction logic circuit that includes a bank control logic coupled to the prediction array. The bank control logic assures the conflict noted above is avoided. The prediction array preferably comprises multiple (e.g., 4) single-ported bank memory elements, each bank comprising multiple predictions. The bank control logic uses information associated with a previously fetched and branch predicted conditional branch instruction to generate a bank number for a current branch instruction. The generated bank number corresponds to one of the banks in the prediction array. The processor preferably fetches two (or more) groups (also called “slots”) of instructions each cycle. Each slot may include one or more branch instructions that need to be branch predicted. Thus, the branch prediction logic circuit first generates a bank number for one of the slots and then generates a bank number for the other slot and uses the bank numbers to retrieve predictions from the multi-bank, single ported prediction array. The bank control logic computes the bank numbers in a manner that assures that no two consecutively generated bank numbers are identical.

摘要： A method for limiting peak-to-average power of a signal transmitted from a power amplifier. The method comprises: applying a pulse-shape filter to a first signal, thereby generating a second signal being a filtered version of the first signal; and outputting the second signal for transmission from a power amplifier. The method further comprises: applying each of a plurality of predictor filters to a respective instance of the first signal, each predictor filter approximating the application of the pulse-shape filter to the first signal based on a different respective set of filter coefficients, and each thereby generating a respective third signal. The method also further comprises determining an indicator of amplitude of each of the third signals, selecting the indicator corresponding to the largest of those amplitudes, generating a modifier based on the selected indicator, and using the modifier to limit the first signal prior to applying the pulse-shape filter.
