Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: A power management method includes generating a power related value; notifying a power management controller if the power related value has passed a threshold; and performing a power control operation by the power management controller. The power control operation prevents an over current event.

Abstract: An electronic system includes a plurality of function modules, each of the plurality of function modules operates according to one of a plurality of clock signals; and a clock management module, for generating the plurality of clock signals according to a plurality of performances requirements of the plurality of function modules.

Abstract: Techniques related to loading-based dynamic voltage and frequency scaling are described. A method may involve measuring a loading of a first power domain. The first power domain may include one or more circuit sections each of which operating in one of a plurality of loading states. The measuring of the loading of the first power domain may involve determining a respective loading state of each of the one or more circuit sections of the first power domain. The measured loading of the first power domain may be representative of a combination of the one or more loading states of the one or more circuit sections. The method may also involve determining at least one operating parameter of the first power domain according to the measured loading of the first power domain.

Abstract: An electronic device includes a first functional block, a second functional block, and a control circuit. The first functional block has a first wake-up guard time requirement. The second functional block has a second wake-up guard time requirement which is different from the first wake-up guard time requirement. The control circuit is coupled to the first functional block and the second functional block, and implemented for selectively controlling the first functional block to switch from a normal mode to a power-saving mode by referring to the first wake-up guard time requirement, and selectively controlling the second functional block to switch from the normal mode to the power-saving mode by referring to the second wake-up guard time requirement.
