    摘要: This disclosure describes techniques for reducing power consumption of a display device. According to these techniques, a display device is configured to determine whether an image to be displayed by the display device has become static. In response to identifying such a static image, the display device may operate in a static image mode. According to the static image mode, the display device may read a current frame of image data, modify the current frame of image data to generate a modified frame of image data with a reduced size, and store the modified image data in memory. The display device may read the modified image data from memory to present the static image, which may reduce power consumption of the display device.

    摘要: A method for clock modeling in a simulation tool is described. An internal time (I) may be defined that governs the simulator tool's clock period. An external time (E) may be defined. The internal time may have a smaller resolution than the external time. A calibration period (C) may be defined for the clock. The calibration period may be smaller than 0.5E and greater than I. The largest inaccuracy of any clock edge may be monitored, and the clock may be calibrated if the largest inaccuracy is greater than (C−1).

    摘要: Methods and apparatus for implementing a Dynamic Voltage Scaling (DVS) system are presented herein. In one embodiment, an embedded delay checker (EDC) cell is used to measure the actual activity and delay of a critical path within a microprocessor core, which is the basis for dynamically altering the voltage to the core. In another embodiment, a slaved ring oscillator (SRO) cell is placed adjacent to the microprocessor core and is used along with EDC cells to provide redundancy to a DVS system.

    摘要: An apparatus for simulating digital systems is described. The apparatus includes a processor and memory in electronic communication with the processor. Instructions that are executable by the processor are stored in the memory. A simulation tool is started. The simulation tool is capable of simulating a plurality of components. A clock phase is adjusted to be turned off for at least one of the components. A digital system is simulated that includes the at least one component. The simulation does not simulate the clock phase for the at least one component.

    摘要: A main die and a stacked die are included in the same component package. A transmission gate (370) is implemented on the main die, and can be enabled to receive leakage current in a connection (318) between the main die and the stacked die, and to conduct the leakage current to a bonding pad (344) that is accessible external to the package. Thus, the connectivity between the main die and the stacked die can be tested after the dies are packaged. The transmission gate is disabled during high-speed testing and normal operation. The package can also include a multiplexer (364) that is enabled during high-speed testing to input and output test signals at the package level. A direction signal is used to indicate whether test signals are being input to or output from the main die.
