  • Patent number: 8760202
    Abstract: A system for generating a clock signal includes a phase-locked loop (PLL) and a voltage storage circuit. The PLL includes a voltage-controlled oscillator (VCO) that generates a clock signal based on a control voltage. The voltage storage circuit includes a unity-gain amplifier (UGA) and first, second and third switches. The first switch connects an input terminal of the UGA and an input of the VCO to sample the control voltage before the PLL transitions from RUN mode to STOP mode. The second switch connects the input and output terminals of the UGA to store the sampled control voltage when the PLL is in STOP mode. The third switch connects the output terminal of the UGA to the input terminal of a low pass filter (LPF) to provide the stored control voltage to the LPF when the PLL transitions from the STOP mode to the RUN mode.

  • Patent number: 8762898
    Abstract: An approach is provided in which an enhanced routing module creates connection objects on a double patterning layout that are correct-by-construction and do not require a semiconductor fabrication stitching process. The enhanced routing module efficiently tracks accumulated mask selection constraints, during maze expansion, when the enhanced routing module traverses possible connection routes from a source grid point to a target grid point. In turn, the enhanced routing module avoids grid points that impose mask selection constraints that are incompatible with existing mask selection constraints of the possible connection routes. As a result, a connection object created by any one of the possible connection routes can be assigned to a specific mask, thus avoiding stitching process requirements from a semiconductor fabrication facility.

  • Patent number: 8762922
    Abstract: A system for reducing leakage power of an electronic circuit design, where the circuit design includes multiple timing paths, each timing path made up of multiple cells, using an electronic design automation (EDA) tool. The EDA tool includes a processor that chooses a first replacement cell for replacing a first cell in a first timing path when timing slack is not available in the first path, where a width and threshold voltage of the first replacement cell are greater than a width and threshold voltage of the first cell. The processor then replaces the first cell with the first replacement cell when the overall power consumption of the first replacement cell is less than that of the first cell, and when the timing slack is available for replacing the first cell with the first replacement cell.

  • Patent number: 8756446
    Abstract: A microprocessor has a low-power mode and a non-low power mode. The microprocessor includes a processor core for executing instructions provided to the microprocessor and a clock providing a clock signal, which in the non-low power mode has a first frequency and in the low power mode has a second frequency lower than the first frequency. A hardware timer is present, for scheduling an execution of an event by the microprocessor at a future point in time. The hardware timer is connected to the clock for determining a period of time between a current point in time and a point in time the event based on a number of clock cycles of the clock signal. A timer controller can determine, when the data processing system switches from the low power mode to the non-low power mode, a number of clock cycles of a clock signal with the first frequency that corresponds to a low-power mode period during which the microprocessor has been in the low power mode and adjusting the hardware timer based on the determined number.
