The present invention is a kind of method of saving the computing machine electric energy by control internal memory throttling (memory throttling), the method is at Basic Input or Output System (BIOS) (the Basic Input/OutputSystem of computing machine, BIOS) add suitable program code in, to set the buffer of north bridge (north bridge), enable the function of (enable) internal memory throttling (memory throttling).
The inventive method is to finish by the internal memory throttling function of setting north bridge, in general chipset (chipset) comprises two chips, wherein north bridge (north bridge) is high frequency range part, with processor, Installed System Memory is connected with viewing hardware, because north bridge needs many pins, so north bridge it seems that volume is bigger, comprise a large amount of signal wires owing to lead to the interface of processor and internal memory, when the encapsulation north bridge chips, also need to prepare a large amount of pins, because north bridge chips has determined processor, the flow velocity of data between internal memory and display device, and comprised the interface that leads to Installed System Memory, the also use of restriction system internal memory is so also have tangible influence to the function of system.
North bridge chips mainly is the influence of systemic-function: the data frequency range of internal memory frequency range, bulk delay (latency), indivedual delay memory, the data frequency range that connects display device and connection south bridge, under the multitask working environment, by north bridge (north bridge) when going to read and write main memory data, can reduce the internal memory processing time, and then make transfer function that the lifting of highly significant be arranged, therefore, the present invention will utilize this characteristic to realize the electricity-saving function that present system manufacturer does not provide.
Because Intel does not support to be set up on their own by window (windows) the internal memory throttling function of north bridge chips, so provide the user to adjust the option of this function voluntarily without any product at present, though some chipset provides this function at present, but because this function does not influence normal running, so among the BIOS and this function of un-activation, though or opened this function, can't select voluntarily by the user.If internal memory throttling (memory throttling) function that operating system supporting chip group is provided then can reduce the processing frequency range of internal memory, reach the effect of power saving.
The feasibility of method proposed by the invention now is described with a preferred embodiment, Figure 1 shows that the present invention passes through the process flow diagram that the method for computing machine electric energy is saved in the internal memory throttling:
The system information of general personal computer is to be recorded in non-volatile random access memory, this NVRAM can be complementary metal oxide semiconductor (Complementary Metal-OxideSemiconductor, CMOS), the information that writes down in the middle of NVRAM comprises the kenel of general hard disk, track number, the sector number of each rail, the magnetic surface number of record data, and system time, date, the number of floppy disk and capacity, the display kenel, information such as amount of memory, usually these setting values can be learnt from Basic Input or Output System (BIOS) or change, BIOS is burning program in the flash memory (flash memory) in motherboard, every hardware in its meeting logger computer, and playing the part of communication bridge with operating system, this program can not lost data because of shutdown, the BIOS of most high level computers supports electricity-saving function, BIOS also provides the interface between operating system and the hardware in addition, need use the equipment of some hardware when operating system, promptly can handle by BIOS, the present invention adds suitable program code in the Basic Input or Output System (BIOS) of computing machine, to set the buffer (Register) of north bridge (NorthBridge is as the Brookdale-M GMCH of Intel).
The step of the inventive method is: read user's setting value (step 100) by NVRAM earlier, set north bridge buffer (step 110) according to this setting value again, carry out electric power (the Power onSelf Test that tests oneself again, POST) (step 120), carry out BIOS and set (setup) program (step 130), call interruption handling procedure (step 140), send an interrupt request (interrupt vector of this interrupt request is INT10h), after interruption is sent, display setting (setup) picture and option (step 150) are selected for the user, person to be used selects to finish, the selection result that stores the user again is to NVRAM (step 160), and activation system (reboot system) (step 170) again, give operating system (Operation system with control, OS) (step 180), like this, the user can be according to needs or the behaviour in service of oneself, decide in its sole discretion and whether enable (enable) this function, as long as the user enters the set-up function (as the F10Setup of BIOS) of BIOS, can finish the switching that internal memory throttling (memorythrottling) is enabled (enable) or do not enabled (disable), quite flexible in the use.
Fig. 2 is user's operational flowchart of the present invention, and its step is as follows:
This process flow diagram illustrates execution in step of the present invention from user's angle, after the user opens computing machine (step 200), at first enter BIOS and set picture (step 210), and selection set of options value (step 220), wait to have set whether enable internal memory throttling (memory throttling) after, leave BIOS again and set picture (step 230).
General user is when using a computer, if want to prolong the running time of notebook computer, then can select whether to enable the function of (enable) internal memory throttling voluntarily, if desire is carried out animation, then can close this function, or work as product at exploitation and test phase, owing to need consider the situation ((worstcase) of poor efficiency, product development and tester also can be by functions proposed by the invention, the internal memory throttling is closed, to carry out temperature (thermal), electromagnetic interference (EMI) (electromagnetic interference, EMI), battery life tests such as (battery life).
