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.

Abstract: A method and a computer-readable medium for dynamically managing power of a multi-core processor of a computing system are provided. The multi-core processor generates a dynamic voltage and frequency scaling (DVFS) table, determines a first index by alternatively selecting either a power budget or a required performance thereof, determines a current thread level parallelism (TLP) of the computing system, selects one of entries according to the current TLP and the first index, and configure first cores and second cores thereof according to a first settings and a second settings of the selected entry.
