Abstract: A task scheduling method for a multi-core processor system includes at least the following steps: when a first task belongs to a thread group currently in the multi-core processor system, where the thread group has a plurality of tasks sharing same specific data and/or accessing same specific memory address(es), and the tasks comprise the first task and at least one second task, determining a target processor core in the multi-core processor system based at least partly on distribution of the at least one second task in at least one run queue of at least one processor core in the multi-core processor system, and dispatching the first task to a run queue of the target processor core.

Abstract: A method for performing processor resource allocation in an electronic device is provided, where the method may include the steps of: obtaining task-related information to determine whether a task of a plurality of tasks is a heavy task (e.g. the heavy task may correspond to heavier loading than others of the plurality of tasks), to selectively utilize a specific processor core within a plurality of processor cores to perform the task, and determining whether at least one scenario task exists within others of the plurality of tasks, to selectively determine according to application requirements a minimum processor core count and a minimum operating frequency for performing the at least one scenario task; and performing processor resource allocation according to a power table and system loading, to perform any remaining portion of the plurality of tasks. An apparatus for performing processor resource allocation according to the above method is provided.

Abstract: Frame running time of a device is estimated dynamically. The device includes a processor that executes threads of an application, and a graphics processor that receives commands from the processor for rendering frames. For each frame, the processor records a timer period for each thread in a set of threads that contribute to operations of a render thread. The render thread writes the commands for the graphics processor to render the frames. Each thread in the set of threads has a corresponding timer that controls a sleep state of the thread. The processor calculates a frame non-running time for a current frame using recorded one or more timer periods, and calculates the frame running time for the current frame by subtracting the frame non-running time from an end-to-end frame period.

Abstract: A multi-core processor system and a method for assigning tasks are provided. The multi-core processor system includes a plurality of processor cores, configured to perform a plurality of tasks, and each of the tasks is in a respective one of a plurality of scheduling classes. The multi-core processor system further includes a task scheduler, configured to obtain first task assignment information about tasks in a first scheduling class assigned to the processor cores, obtain second task assignment information about tasks in one or more other scheduling classes assigned to the processor cores, and refer to the first task assignment information and the second task assignment information to assign a runnable task in the first scheduling class to one of the processor cores.
