  • Runtime power table index adjustment for performance and power management
    Patent number: 10921876
    Abstract: Power and performance of a multi-core system is managed dynamically by adjusting power table indices at runtime. Runtime statistics is measured, when an application is executed on a first core of a first type at a first operating point (OPP) in a first time period, and on a second core of a second core type at a second OPP in a second time period. A controller estimates, based on the runtime statistics, a first pair of indices associated with a first OPP for the first core and a second pair of indices associated with a second OPP for the second core. During runtime, the controller incorporates the first pair of indices and the second pair of indices into power table indices; and determines, from the power table indices, selected indices associated with a selected OPP of a core of a selected core type for executing the application.

  • Projection system and keystone correction method
    Patent number: 10904501
    Abstract: A projection system and a keystone correction method are provided. The projection system includes: a projector projecting an image to a projection zone; an image capturing device capturing a captured image including the projection zone; and a processor. The processor divides the captured image into multiple focusing zones, and controls a stepper motor to shift focusing on the focusing zones at edges to obtain a step of the stepper motor and a distance for each of the focusing zones with a maximum clarity value. The distance is a projection distance between a lens module and the focusing zone. The processor calculates an included angle between the direction of a light axis of the projector and the projection zone according to the distances of the focusing zones at the edges, and performs a warping operation on a projection image according to the included angle.
