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: A task scheduling method is applied to a heterogeneous multi-core system. The heterogeneous multi-core system has at least one first processor core and at least one second processor core. The task scheduling method includes: referring to task priorities of tasks of the heterogeneous processor cores to identify at least one first task of the tasks that belongs to a first priority task group, wherein each first task belonging to the first priority task group has a task priority not lower than task priorities of other tasks not belonging to the first priority task group; and dispatching at least one of the at least one first task to at least one run queue of at least one of the at least one first processor core.
