International Classification:

G06F 9/48
G06F 9/50
G06F 1/08

Abstract:

In a real-time system having first and second processor systems, cooperative dynamic clock and voltage scaling (“DCVS”) may include a first processor system monitoring a condition indicative of first processor workload, adjusting a first processor operating frequency in response to a detected amount of change in the first processor workload, and providing an indication based on the detected amount of change in the first processor workload to the second processor contemporaneously with providing first processor output data to the second processor. The cooperative DCVS may further include the second processor system adjusting a second processor operating frequency in response to the indication.

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:

User equipment (UE) may benefit from power management techniques, for example, in the context of cellular vehicle-to-everything (CV2X) communication. 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.

International Classification:

H04N 5/232
G06N 3/08

Abstract:

Techniques and systems are provided for machine-learning based image stabilization. In some examples, a system obtains a sequence of frames captured by an image capture device during a period of time, and collects motion sensor measurements calculated by a motion sensor associated with the image capture device based on movement of the image capture device during the period of time. The system generates, using a deep learning network and the motion sensor measurements, parameters for counteracting motions in one or more frames in the sequence of frames, the motions resulting from the movement of the image capture device during the period of time. The system then adjusts the one or more frames in the sequence of frames according to the parameters to generate one or more adjusted frames having a reduction in at least some of the motions in the one or more frames.

International Classification:

G06F 1/20
H01L 25/10

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 second package includes a second substrate and a second die coupled to the second substrate. The TEC is located between the first die and the second substrate. 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:

Systems, methods, and computer programs are disclosed for reducing leakage power of a system on chip (SoC). One such method comprises monitoring a plurality of temperature differentials across a respective plurality of thermoelectric coolers on a system on chip (SoC). Each of the thermoelectric coolers is dedicated to a corresponding one of a plurality of chip sections on the SoC. The thermoelectric coolers are controlled based on the plurality of temperature differentials to minimize a sum of a combined power consumption of the plurality of chip sections and the plurality of corresponding dedicated thermoelectric coolers.

International Classification:

G06F 1/32

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.
