Abstract: Disclosed herein is an apparatus and method for managing a heterogeneous multi-core processor system, which can allocate a core to the execution of an application based on the states of cores included in heterogeneous multi-core processors. The apparatus for managing a heterogeneous multi-core processor system includes a management unit for receiving states of cores included in heterogeneous multi-core processors from an operating system layer and managing the states of the cores. A determination unit determines a core to be allocated to execution of an application among the cores included in the heterogeneous multi-core processors, based on the states of the cores received from the management unit. An allocation unit allocates the core determined by the determination unit to the execution of the application.

Abstract: The present invention relates generally to a task distribution method and apparatus for systems in a real-time Operating System (OS) environment using a multi-core Central Processing Unit (CPU). The present invention is configured to set roles of multiple cores included in the multi-core system in such a way as to divide the cores into real-time cores for executing real-time tasks and non-real-time cores for executing non-real-time tasks, allocate real-time tasks to cores, a role of which has been set to that of real-time cores, and non-real-time tasks to cores, a role of which has been set to that of non-real-time cores, based on the set roles of the cores, allow the respective cores to execute the tasks allocated thereto, and collect information about a procedure of executing the tasks as task execution procedure information, and change the set roles of the cores based on the collected information.

Abstract: Disclosed herein are an apparatus and method for controlling a governor based on a heterogeneous multicore system. The apparatus includes a heterogeneous core cluster unit for running any one of a first core cluster for high-performance operation and a second core cluster for low-power operation by switching therebetween; a governor-setting unit for generating operation setting information of a governor for controlling operation of the first core cluster and second core cluster; and a governor control unit for controlling operation of one or more governors based on the operation setting information.
