Abstract

The invention provides a power budget allocation method and a power budget allocation apparatus, the method comprising: obtaining a system setting associated with a multi-core processor system, wherein the system setting comprises a core combination setting of the multi-core processor system and further comprises a frequency setting of each processor core selected by the core combination setting; 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 power budget allocation method and the power budget allocation apparatus are capable of efficiently adjusting the configuration of the multi-core processor system to meet the target power budget requirement.

Description

technical field [0001] Embodiments of the present invention relate to power management, and more specifically, to a power budget allocation method and a related power budget allocation device for generating power management outputs according to a multi-core processor system and a target power budget. Background technique [0002] A system-on-chip (SoC) of an electronic device requires very high performance, and thus needs to support higher computing power. When the SoC is in a high computing power mode, heat dissipation becomes an important issue due to the small size of the electronic devices. In order to achieve higher computing power, the SoC of electronic equipment can adopt a multi-core processor system. However, multi-core processor systems are a heat source that needs to be monitored. If the temperature of the multi-core processor system exceeds the threshold temperature, the lifetime of the multi-core processor system may be relatively short due to permanent damage...
