CLOCK CONTROL METHOD FOR SoC(SYSTEM ON CHIP) INCLUDING FUNCTION BLOCK, SoC IMPLEMENTING THE SAME AND SEMICONDUCTOR SYSTEM INCLUDING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a clock control method of an SoC(System on Chip) including a function block, the SoC implementing the method and a semiconductor system including the SoC.

SOLUTION: Disclosed is a clock control method of an SoC including at least one or more function blocks and the SoC. The clock control method of the SoC includes the steps of: detecting the first change of the operating state of the function block from an active state to an idle state; decreasing the operation frequency of the function block in response to the detected first change; detecting the second change of the operating state of the function block from the idle state to the active state; and increasing the operation frequency of the function block in response to the detected second change.
