System on chip and operating method thereof

An operating method of a system on chip, the operating method comprising:

• executing an application by using a shared library, the application being supported by an operating system;
• generating control information of a processor for executing a function and predictive performance information of the processor that is predicted during control according to the control information when the function included in the shared library is executed, the control information referencing a history corresponding to the function from a history table;
• and
• generating a control signal for performance control of the processor based on the control information,
• wherein the history is an accumulation of performance information of the processor measured by executing in advance the function at least once.

An operating method of a system on chip, the operating method comprising:

• executing an application supported by an operating system;
• identifying whether a history corresponding to a function used to execute the application is present in a history table;
• generating control information of a processor for executing the function and predictive performance information of the processor that is predicted during control according to the control information when the history corresponding to the function is present in the history table, the control information referencing the history corresponding to the function;
• and
• generating a control signal for performance control of the processor based on the predictive performance information,
• wherein the history is an accumulation of performance information of the processor measured by executing in advance the function at least once.
