Abstract: Techniques described herein provide for filtering and prioritizing incoming messages, which can help reduce and smooth out the processing load on components used to process the incoming messages. Filtering techniques may comprise identifying a subset of nearby vehicles from which messages are to be processed, and further calculating remaining delay budgets with regard to the messages to prioritize them for processing. Different techniques for determining a subset of nearby vehicles can be used, and/or remaining delay budgets may be calculated and/or communicated in different ways.

Abstract: Embodiments include methods for managing the processing of data and performing computing tasks of a wireless device using computing resources of a remote network computing device. A wireless device and a network computing device may dynamically track factors affecting a round-trip latency of a computing task. The wireless device and the network computing device may generate and send metadata including the factors and a latency budget for the computing task. The wireless device and the network computing device may adjust a processing time for processing data related to the computing task based the received metadata and the latency budget.

In various aspects of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE configured to determine whether a first subframe includes at least one sub-channel carrying information intended for the UE, receive the information via at least one receive (Rx) chain associated with the at least one sub-channel when the information intended for the UE is carried on the at least one sub-channel included in the first subframe, and deactivate the at least one Rx chain associated with the at least one sub-channel based on whether the information intended for the UE is absent from the at least one sub-channel included in the first subframe.

Abstract: A low-power state current/power consumption for each volatile memory device in a plurality of volatile memory devices is obtained. Data is copied from a first set of the volatile memory devices to a second set of the volatile memory devices, where the second set of volatile memory devices has a lower current/power consumption than the first set of volatile memory devices. Additionally, a current/power consumption may be obtained for each memory bank within each of the plurality of volatile memory devices. Data is then copied from a first set of memory banks to a second set of memory banks within the same memory device in the second set of memory devices, where the second set of memory banks has lower current/power consumption than the first set of memory banks. The first set of volatile memory devices and/or first set of memory banks are then placed into a power-down state.

Abstract: Various embodiments of methods and systems for energy efficiency aware thermal management in a portable computing device that contains a heterogeneous, multi-processor system on a chip (“SoC”) are disclosed. Because individual processing components in a heterogeneous, multi-processor SoC may exhibit different processing efficiencies at a given temperature, energy efficiency aware thermal management techniques that compare performance data of the individual processing components at their measured operating temperatures can be leveraged to optimize quality of service (“QoS”) by adjusting the power supplies to, reallocating workloads away from, or transitioning the power mode of, the least energy efficient processing components. In these ways, embodiments of the solution optimize the average amount of power consumed across the SoC to process a MIPS of workload.

Abstract: A package-on-package (PoP) device includes a first package, a second package, and a bi-directional thermal electric cooler (TEC). The first package includes a first substrate and a first die coupled to the first substrate. The second package is coupled to the first package.

The TEC is adapted to dynamically dissipate heat back and forth between the first package and the second package. The TEC is adapted to dissipate heat from the first die to the second die in a first time period. The TEC is further adapted to dissipate heat from the second die to the first die in a second time period. The TEC is adapted to dissipate heat from the first die to the second die through the second substrate.

Abstract: A method and system for optimizing a core voltage level of a portable computing device (“PCD”) and enhancing frequency performance of individual subcomponents are disclosed. A plurality of voltage values for a plurality of subsystems is determined. At least one subsystem is a multiplexed subsystem. Next, a reduced set of voltage values is calculated based on the plurality of voltage values and an optimized voltage level is determined for a shared power domain. The shared power domain is subsequently set to the optimized voltage level. If the optimized voltage level is determined to exceed a required voltage level for the at least one multiplexed subsystem when it is running the plurality of processing engines, a subset of the plurality of processing engines may be identified to process a workload of the multiplexed system at a more efficient level of power consumption than the full plurality of processing engines.

Abstract: Systems and methods for dynamically adjusting an input parameter to a power domain in a portable computing device are disclosed. The power domain includes two or more processing resources that share a power source. Dynamic use of the two or more processing resources creates an opportunity to adjust the input parameter when a status change associated with a processing resource in the power domain occurs. A controller in the power domain includes logic that responds to a status indicator associated with a respective processing resource in the power domain by generating a control signal that directs a device to adjust one or both of input voltage and clock frequency.
