APPARATUS FOR CONTROLLING PROCESSOR AND METHOD FOR MEASURING PROCESSOR PERFORMANCE USING SYSTEM CALL

摘要

PURPOSE: A device for controlling a processor using a system call and a method for measuring performance of the processor are provided to control performance of the processor according to a system call pattern, thereby preventing an unnecessary core operation. CONSTITUTION: A controller(520) controls the number of cores(510) changed by a system call pattern of an application executed by a processor. A pattern analyzer(530) analyzes a change of the system call pattern. When the system call pattern corresponds to the first system call pattern for setting the maximum performance of the processor, the controller drives all cores.
