Abstract: When power is provided through a USB-C cable from a source device to a sink device, a sudden connection or disconnection of the cable between the two devices may cause a sudden power surge or power drop in at least one of those devices, leading to other problems. To avoid this sudden event from causing potential damage or disruption to one of the devices, in some embodiments a CC pin in the cable is used to announce the impending connection/disconnection, and the device may throttle back its power consumption before power is actually applied to or removed from the power pins.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can determine if a new frame includes one or more dirty portions. If the new frame includes one or more dirty portions, just the dirty portions can be loaded by the display engine into a display buffer. The display engine can also scan out just the dirty portions from the display buffer to a display.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for reduced computing device power consumption. Example methods disclosed herein includes detecting frame updates corresponding to input frames to be presented by a display, causing a programmable timer to generate second interrupts corresponding to first interrupts generated by a display engine, the second interrupts to be generated when there are no frame updates detected for at least a first duration of time defined by a first threshold. Example methods further include causing the display engine to transition to a low power state when (1) the programmable timer is configured to generate the second interrupts and (2) no frame updates have been detected for at least a second duration of time following the first duration of time, the second duration of time defined by a second threshold.

Abstract: Techniques for selective display frame fetching are disclosed. Some example techniques disclosed herein cause at least one processor to at least determine if an indication of a new frame includes an indication of a flip event, and identify one or more dirty regions of the new frame based on the flip event. Disclosed example techniques also cause the at least one processor to fill a display buffer with the one or more dirty regions of the new frame, scan out the one or more dirty regions of the new frame from the display buffer to a display port, and apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

Abstract: Techniques for selective display frame fetching can include receiving or fetching rendered display frames by a display engine. The display engine can obtain an indication of a new frame and, in response to the indication of the new frame not including an indication of a flip completion event: (i) fill the display buffer with the new frame; (ii) scan out the new frame from the display buffer to a display port; and (iii) apply an adaptive contrast and backlight enhancement based on a histogram of changes in the new frame.

Abstract: Apparatus, systems, and methods for intelligent tuning of overclocking frequency are disclosed. An example apparatus includes trial control circuitry to execute an optimization model to select first values for overclocking parameters of a processor, the first values associated with a first trial, and perform benchmark testing of the processor when the processor is operating based on the first values; trial evaluation circuitry to calculate a first score for the first trial based on the benchmark testing; and model updating circuitry to perform a comparison of the first score to a second score, the second score associated with a second trial for second values for the overclocking parameters, the second values different than the first values; and select one of the first values or the second values to overclock the processor based on the comparison.
