Problems solved by technology

[0009] The purpose of the present invention is to overcome the defects in the existing processing method of the central processing unit and provide a new power saving method for the central processing unit. The technical problem to be solved is to make the central When the peripheral device sends a bus master request event, the processor enters the dormant state where the event can be peeped, so as to process the bus master request event, so as to achieve the purpose of power saving, which is more suitable for practical use

Embodiment Construction

[0052] For further elaborating the technical means and effects that the present invention takes to reach the intended invention purpose, below in conjunction with accompanying drawing and preferred embodiment, to the power-saving method of the central processing unit that proposes according to the present invention and system its specific implementation, method , step, structure, feature and effect thereof, detailed description is as follows.

[0053] The present invention proposes a power-saving method and system for a central processing unit, so that the central processing unit enters the C2 state where the event can be peeped when it cannot peep into the C3 state of the event and receives the request event from the bus master controller, so as to peep and process the event The bus master requires events to resolve the above problems.

[0054] see figure 2 Shown is a block diagram of an embodiment of the present invention. As shown in the figure, the power saving system o...

Abstract

The invention is about a method to save electricity of the CPU and the system. The method is to make the CPU leave the resting state of unsighting things firstly, then to prevent the reflex message transfer to CPU, last to make the CPU in the sighting resting state and start the arbitration equipment and transfer the commanding things of the bus-bar mater controller to the CPU to treat. So it can save the energy of the CPU and the computer energy. The system includes arbitration equipment and a system wafer; the CPU leaves the resting state according to the first controlling message and goes into the treating state; then it goes into the resting state to treat the commanding things of the bus-bar mater controller.

Description

technical field [0001] The present invention relates to a method and system for saving power of a central processing unit, in particular to a method and system for saving power of a central processing unit when an event required by a bus master controller occurs in a dormant state where the central processing unit cannot peep into events . Background technique [0002] In today's life, electricity is one of the indispensable energy sources, and all the electrical appliances you see around you need power to operate. It is conceivable that if there is a lack of power supply, life will become quite inconvenient. Therefore, in order to avoid power shortage caused by excessive power consumption, all kinds of electrical appliances now pay attention to high efficiency and power saving. Computers (computers are computers, hereinafter referred to as The same is true for computer) systems, especially notebook computers. [0003] Current computer systems, such as personal computers o...
