20110218779 | Identification of Critical Enables Using MEA and WAA Metrics - A plurality of sequential nodes in a design file for an electronic device are identified and one or more combinatorial power metric values are computed for the plurality of sequential nodes based upon an effective switching capacitance, a switching activity measure, and a power effort measure for at least a first device downstream from the each sequential node at a specified depth. The combinatorial power metric values for the plurality of sequential node are stored and compared to a target power metric value to determine if power consumption at the electronic device meets a predetermined power performance goal. | 09-08-2011 |
20110261064 | 10T SRAM FOR GRAPHICS PROCESSING - A method, apparatus, computer chip, circuit board, computer and system are provided in which data is stored in a low-voltage, maskable memory. Also provided is a computer readable storage device encoded with data for adapting a manufacturing facility to create an apparatus. The method includes storing a data value in a memory cell in a storage device if a first access parameter associated with the memory cell matches a first pre-determined value and if a second access parameter associated with the memory cell matches a second pre-determined value. The method also includes maintaining a data value in the memory cell in the storage device if the first access parameter differs from the first pre-determined value. The apparatus includes a first and second pair of access parameter ports operatively coupled together and associated with a first and second access parameter respectively. The first and second pair of access parameter ports may be adapted to allow access through the first and second pair of access parameter ports if the first access parameter matches a first pre-determined value, and if the second access parameter matches a second pre-determined value. | 10-27-2011 |
20120187991 | CLOCK STRETCHER FOR VOLTAGE DROOP MITIGATION - A clock frequency of a clock signal used by a processor may be temporarily reduced to compensate for voltage droops in the power supply to the processor. A device may include a multiplexer to receive a group of phase shifted versions of the clock signal and to output one of the group of phase shifted versions of the clock signal as an output clock signal. A control component may receive the output clock signal from the multiplexer and a voltage droop event signal indicating whether a voltage droop event is occurring in a power supply. The control component may control, in response to the voltage droop event signal indicating the occurrence of the voltage droop event, the multiplexer to iteratively select the group of phase shifted versions of the clock signal to reduce the frequency of the output clock signal. | 07-26-2012 |
20140223199 | Adaptive Temperature and Power Calculation for Integrated Circuits - Methods, apparatus, and fabrication processes relating to thermal calculations of an integrated circuit device are reported. The methods may comprise determining a power consumption by a power entity of an integrated circuit, the power entity comprising at least one functional element of the integrated circuit; determining a temperature of a thermal entity, the thermal entity comprising a subset of the power entity; and adjusting at least one of a voltage or an operating frequency of at least one functional element of the power entity, based upon the temperature of the thermal entity being greater than or equal to a predetermined threshold temperature for the thermal entity. | 08-07-2014 |
