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.

Abstract: An apparatus and method for monitoring the performance of cores based on a multi-core processor. The apparatus includes a status information collection unit and a monitoring unit. The status information collection unit collects a plurality of pieces of status information extracted from respective cores, and stores the plurality of pieces of status information in respective memory areas provided for the cores. The monitoring unit receives the status information, sends the status information to a storage unit, and performs monitoring based on the status information. The monitoring unit is provided in any one of the cores.
