Description
[Ji Intraoperative field]
The present invention is relevant for a kind of power management techniques, particularly relevant for a kind of electronic installation of tool electric power management mechanism.
[Bei Jing Ji Intraoperative]
Gordon's mole (Gorden Moore) that proposes Moore's Law (Moore ' s law) thinks that integrated circuit (IC) goes up open ended transistor size, just can double every 18 months approximately, performance also will promote one times, and transistor up to a million and copper cash have been comprised on the present integrated circuit (IC), the integrated circuit of this complexity (IC) structure then can relatively increase more power consumption problem, in addition, because of computer speed and functional requirement constantly promote, cause the demand of electric power to promote more thereupon, therefore in the electronic installation administrative skill of power supply real be important, relative CPU (central processing unit) (CPU) also become more important for the support design of powder source management mode; In addition, except that general personal computer system or server system use the power management techniques, embedded system also utilizes power management techniques to reach energy-conservation effect, makes and utilizes the designed associated electrical products such as action hand-held device of embedded system also can have service time more of a specified duration.
Yet, be not that all its CPU (central processing unit) that adopts of electronic installation are all supported powder source management mode, the arithmetic processor that also is not all employings all can enter in the park mode (deep sleep mode) of more power saving, therefore lower stand-by time and system's availability of electronic installation unavoidably, be the design of the embedded system of a large amount of exploitations now still more, be used for PDA(Personal Digital Assistant) in a large number, the diverse network relevant device, mobile phone, digital camera, digital camera, reach in the system of Digital Television or the like associated electrical product, the power consumption degree of its arithmetic processor is considered more important.But,, so will influence the efficient of system works and the reliability that electric weight is crossed its system when hanging down because the different influences of considering of each tame chip designer or encapsulation procedure make not to be all problem generations of dormant mode support of arithmetic processor.
The CPU (central processing unit) (for example: Samsung 2440 or Samsung2410 etc.) that can't enter park mode with some is the system of platform, system is crossed when low at battery electric quantity, because can oneself not enter park mode, and the system that makes can use battery electric quantity unexpected powered-down when too low the user, and work as system in the electric power abundance, but can find real-time clock module (the real timeclock module of system when starting shooting again; RTC module) data of being managed is destroyed, and this kind problem is most commonly at present as on the hand-held action devices such as mobile phone, PDA(Personal Digital Assistant).
Therefore, take off the existing problem of technology before how effectively solving, and develop the technical scheme of a tool electric power management mechanism, with the power supply of effective managing electronic device and when avoiding closing suddenly because of the power supply of electronic installation, the thing that the data that cause real-time clock module to manage are lost, the problem that present just power-supply management system is needed to be resolved hurrily.
[summary of the invention]
