Abstract: An integrated circuit (IC) configurable to perform adaptive thermal ceiling control in a per-functional-block manner, an associated main circuit, an associated electronic device and an associated thermal control method are provided. The IC may include a plurality of hardware circuits arranged to perform operations of a first functional block, and at least one thermal control circuit. At least one temperature sensor is coupled with the first functional block to detect temperature and to generate at least one temperature sensing result of the first functional block. The thermal control circuit performs thermal control on the first functional block to prevent the first functional block from overheating and inducing abnormal function operations, by monitoring the temperature sensing result and by trying to prevent the temperature sensing result from exceeding first temperature upper-limit, wherein the first temperature upper-limit is configurable with respect to per-functional-block thermal operation capability of the first functional block.

Abstract: A multi-processor system performs thermal-aware task scheduling and task migration. Based on temperature measurements, the system determines one or more thermal conditions of each processor. The thermal conditions include a present temperature, a historical temperature, a predicted temperature, and thermal headroom of the processor. A scheduler identifies a target processor among the processors based on, at least in part, the one or more thermal conditions of each processor, and assigns a task to be executed by the target processor. For task migration, the system detects that a source processor satisfies a task migration criterion by comparing one or more of the thermal conditions of the source processor with corresponding thresholds. The scheduler identifies a target processor based on, at least in part, one or more of the thermal conditions of each processor, and migrates a task from the source processor to the target processor for execution.

Abstract: A power budget allocation method includes: obtaining a system setting associated with a multi-core processor system, obtaining a target power budget, and checking, by a power management controller, at least one power management table according to the system setting and the target power budget to generate a power management output for the multi-core processor system. The system setting includes a core combination setting of the multi-core processor system, and further includes a frequency setting of each processor core selected by the core combination setting.
