METHOD TO CONTROL A COMPUTER HAVING AN ADJUSTABLE CLOCK GENERATOR AND A MICROPROCESSOR SYSTEM

摘要

A microprocessor system has a clock (14, 12) for generating a variable clock frequency. There is a process table (19) containing information of processes of the microprocessor system where the information of each process comprises a specific process load information. A clock frequency is calculated from the specific process load information of the processes called and stopped. The clock is controlled to generate a clock frequency corresponding to the calculated clock frequency, thereby reducing the power drain requirement to a minimum value required for the processes called.
