摘要： Dynamic frequency and voltage scaling for a computer processor, including retrieving information specifying a nominal operating point of frequency and voltage and an operating range of frequency and voltage for the processor; creating, by the power management module dynamically at run time in dependence upon the retrieved information, a table of frequency, voltage pairs, each pair specifying an operating point of frequency and voltage for the processor, each pair disposed upon a line drawn in frequency-voltage space through the nominal operating point between the minimum operating point and the maximum operating point, the distance between each pair defined in dependence upon a minimum change in power supply voltage supported by the power supply; and selecting and applying, by the power management module from the table, an operating voltage and frequency for the processor in dependence upon current operating conditions of the processor.

摘要： A mechanism is provided for minimizing system power in a data processing system. A management control unit determines whether a convergence has been reached in the data processing system. If convergence fails to be reached, the management control unit determines whether a maximum fan flag is set to indicate that a fan is operating at a maximum speed. Responsive to the maximum fan flag failing to be set, a thermal threshold of the data processing system is either increased or decreased and thereby a fan speed of the data processing system is either increased or decreased based on whether the system power of the data processing system has either increased or decreased and based on whether a temperature of the data processing system has either increased or decreased. Thus, a new thermal threshold and a new fan speed are formed. The process is then repeated until convergence has been met.

摘要： Method and apparatus for determining occurrence of an S1 modem identification sequence is disclosed. An S1 sequence is found to exist when the sum of conjugate complex multiplication of signal sample amplitudes taken at an interval T/2 result in a negative scalar value for an arbitrary number of sequential occurrences. Complex samples taken from incoming baseband waveform at twice the modulation rate are interleaved in pairs of two with two even numbered samples and two odd numbered samples being considered separately by first performing complex multiplication followed by scalar multiplication of an output of the complex multiplication and an output of the previous complex multiplication delayed by one modulation interval T. The separate results from the sets of pairs of signal samples are summed to form a scalar whose value when consistently less than 0 indicates the presence of an S1 modem identification sequence in accordance with the CCITT S1 recommendation.
