POWER MANAGEMENT SYSTEM FOR INTEGRATED CIRCUIT

摘要

PROBLEM TO BE SOLVED: To easily structure the power managing mechanism of the whole integrated circuit system without redesigning a block. SOLUTION: This power management system for the integrated circuit is equipped with a signal line, a management information generation part which is connected to the signal line, and multiple management information use parts which are connected to the signal line respectively. The management information generation part outputs to the signal line power management information for managing the power consumption of the management information uses parts corresponding to the state of the management information generation part and each management use part reads common power management information out of the signal line and controls the electric power that the management information use part consumes according to the electric power management information.
