Abstract: One or more components of a computing device are run by default in a boost mode state. The one or more components continue to run in the boost mode state until the boost mode state is no longer sustainable, e.g., due to power consumption of the one or more components or temperature of the one or more components. The one or more components are switched to a reduced power state (e.g., a non-boost mode state) in response to the boost mode state no longer being sustainable. When operating the one or more components in the boost mode state again becomes sustainable due to power consumption or temperature of the one or more components, the one or more components are returned to the default boost mode state.

Abstract: Adjustable thermal management is described. Input to adjust one or more parameters for controlling thermal conditions of a component is received. Temperature measurements of a component are obtained from two or more sensors of the component. A temperature of a thermal hotspot of the component is estimated based on the temperature measurements obtained from the two or more sensors of the component and using the adjusted parameters. Operation of the component is adjusted based on the estimated temperature of the thermal hotspot.

Abstract: Task scheduling based on component margins is described. In accordance with the described techniques, a scheduler of an operating system accesses a margin table when a request to perform tasks is received. The scheduler schedules tasks on various components of a system based on margins of those components. When a request to perform a task is received, for example, the scheduler accesses the margin table and selects a component to perform the task based on the margin information included in the margin table as well as based on the task, such as whether the task benefits more from being performed fast or being performed accurately. The scheduler then schedules the task using the selected component.

Abstract: Dynamic range aware conversion of sensor readings is described. A system includes one or more sensors to sense conditions of a component and output sensor readings and a system manager.

The system manager then adjusts operation of the component based on the condition measurements.

Abstract: Circuits, methods, and apparatus that can provide detector arrays that are able to avoid or limit saturation of SPAD devices from both ambient and reflected light while maintaining sufficient sensitivity to generate a lidar image. An example can provide a SPAD device having high dynamic range. This SPAD device can include a first cathode for a first diode and a second cathode for a second diode formed in a common anode, where the common anode can be formed of an epitaxial layer. When high sensitivity is desired, both the first diode and the second diode can be biased above their breakdown voltage. When a lower sensitivity is desired, the first diode can be biased above its breakdown voltage while the second diode can be biased below its breakdown voltage. Diode bias voltages can be tuned to steer photogenerated carriers towards the second cathode to further reduce sensitivity.

One example can provide a lidar system having emitter elements to emit optical signals and sensor elements to detect incident photons. The emitter elements can emit a first optical signal having a series of pulses at a first power level and a second optical signal having a series of pulses at a second power level. Following first pulses, the sensor elements can determine a number of photons detected during a first number of time bins that begin with an initial time bin and extend to a first time bin. Following the second pulses, the sensor elements can determine a number of photons detected during a second number of time bins beginning with the initial time bin and extending to a second time bin. The second power level can differ from the first power level and the second number can differ from the first number.
