Abstract: Various aspects of a power management approach for a system-on-a-chip (SoC) is disclosed herein. In one aspect, the approach includes implementing a power profile for supplying power to a plurality of subsystems on a shared power bus in the SoC. The power profile includes at least one adjustable parameter for controlling the supplied power during an active use state. The approach further includes detecting a power profile change trigger; modifying the power profile based on the power profile change trigger; and adjusting the supplied power during the active use state based on the modified power profile to maintain a predetermined supplied power level.

Abstract: The reliability of a data communication link may be analyzed and otherwise maintained by collecting a two-dimensional array representing a functional data eye, and using a convolutional neural network to determine a score of the functional data eye. The determined score may be compared with a threshold, and an action may be initiated based on the result of the comparison.

Abstract: A particular method includes, prior to issuing a recommendation by an adaptive voltage scaling (AVS) system, performing a first iteration of an AVS operation to sample characteristics of a semiconductor device to determine a first adjustment recommendation. The method further includes performing at least one additional iteration of the AVS operation to determine at least one additional adjustment iteration. When a threshold number of consecutive adjustment recommendations are consistent, the method includes issuing the recommendation by the AVS system.

Abstract: A thermal controller for managing thermal energy of a multi-core processor is provided. The cores include a first core processing a load and remaining cores. The thermal controller is configured to determine that a temperature of the first core is greater than a first threshold, determine a temperature of a second core of the remaining cores in response to determining that the temperature of the first core is greater than the first threshold, and determine whether the temperature of the second core is greater than or less than a second threshold. The thermal controller is configured to transfer at least a portion of the load of the first core to the second core in response to determining that the temperature of the first core is greater than the first threshold and based on whether the temperature of the second core is greater than or less than the second threshold.

Abstract: A method, an apparatus, and a computer program product are provided. The apparatus may be a UE. The UE has a processor including a plurality of cores. The plurality of cores includes a first core and remaining cores. The UE determines a temperature of the first core of the plurality of cores. The first core processes a load. The UE determines that the temperature of the first core is greater than a first threshold. The UE determines that the temperature of the first core is not greater than a second threshold. The second threshold is greater than the first threshold. The UE transfers at least a portion of the load of the first core to a second core of the remaining cores in response to determining that the temperature of the first core is greater than the first threshold.
