Abstract: A task scheduling method is applied to a heterogeneous multi-core processor system. The heterogeneous multi-core processor 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.
