System and method for dynamically controlling processing speed of a computer in response to user commands

摘要

When a user instructs acceleration or deceleration of the CPU processing speed with an "accelerator" button or a "brake" button, a speed control MMI informs power management system software of the corresponding information to change the CPU processing speed. The change is recorded on a speed management database in correspondence with the name of the application program which is currently being executed. Every time acceleration or deceleration of the CPU processing speed is instructed by the user, speed management data is formed on the speed management database. By using the speed management data, the CPU processing speed can be dynamically controlled for each piece of software when it is executed. Further disclosed is a novel power dissipation control system for a microprocessor, adapted to be used in conjunction with the above described MMI.
