Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for reducing power consumption for reducing power consumption of a portable device. [Prior Art] Derivative 1 = Technical Progressive 'Traditional portable and lightweight features have been provided by the user for the basic or complete needs of the featured features. Lack of ίο 15 in the development of traditional portable device systems..., operating systems and single-specific functions, related applications == related development, and then by + central == vendor μ / 〈 benefits (LPU) or specific Application of crystal PP lcatl- Spec.fic Integrated Circuit > ASIC) The system of the fASIC system is also called embedding w(10) mobile power 1 ^ for richer functions, traditional portable devices (eg: -IS mobile phones, or individuals) Mobile Assistants are all versed in a variety of applications. The application executed by the industry and the Γ1Γ device can be divided into foreground essays*. The job of the job is: ······························································ ^ The system of the device is in the general state to provide this application: the application of the period tl 冼 源 source 'month view operation includes: noisy tips, : period address update (perlQdlel. (10) 1Gnupdate), time synchronization and more Input signal, screen update, etc. When the background job application is not executed, the traditional portable system is in standby mode to save 20 1312470 2 resources, and wait for the segment trigger time, the central processor is connected ^ And make the traditional portable device (4) from the standby state (four) to the general:::: two applications. As shown in FIG. 1, it is assumed that the application of the h job that the conventional portable device has set includes: periodic bit 5 10 15 1), time synchronization update (work 2), and honor screen update (work =, = The security address of the address update is executed every 45 seconds _ times 'time synchronization two work cycle is executed every 2G seconds - screen update work :: ::, execute once 'in order to ensure the application of the above background work The program is executed effectively. The traditional portable device sets all the working week time (5 seconds). After waiting for a time slot time, the traditional portable device switches from the standby state to the normal state and checks the background to be executed. If the work corresponding to the application of the job is completed, if it is not established, the process will be switched from the normal state to the standby state, and after another time slot time, the above operation will be repeated. Although the application executing the foreground job will consume More system resources are relatively less likely to execute and therefore consume a small amount of resources; applications that perform background operations will consume less system resources, but The cycle is fixed and repeated, and the accumulated system resources are consumed more. Therefore, if the system resources consumed by the application executing the background job can be reduced, the traditional portable split can be directly/indirectly extended. Working hours. Therefore, there are a number of documents that disclose ways to reduce power consumption, for example, US Patent No. 5,487,181, patent name rLOW POWER ARCHITECTURE FOR PORTABLE AND MOBILE TWO-WAY RADI0S, which discloses the traditional portable 20 1312470 The device can be switched between the two modes of operation, respectively as the main mode) and the software standby building ★ wide, the type (active private P mode (SQftware standby m to reduce the power consumption. Also write the beginning of the credit Only the 4 pairs of micro-processing 5 "construction" can also reduce the power of the traditional portable 1 set: the consumption of the above-mentioned square shirts will be caused by the consumption of the above-mentioned square shirts, but the implementation will be realized. The lack of power consumption of the system device. Effectively solve the traditional portable [invention] 10 To overcome the conventional portable device in the power consumption: dew-type reduction The method of power consumption of the device, the triggering time corresponding to the application of the 15 concurrent application is a '(a)_trigger time to obtain the system'· and (C) in the system cycle, when the touch person 3 has recorded the trigger The application of the background work corresponding to the time is executed to overcome the lack of power consumption of the conventional portable device. A method for reducing the portable device is: (A) the method of hunting for thousands of months The method includes the workflow cycle corresponding to the application of the scene, and the work cycle telephone and the smart phone are executed when the back of the method is used:: mobile: portable portable can be used for action The method of power consumption can be achieved under the system architecture; the purpose of saving the power consumption of the device of the device can be reduced. 25 1312470 [Embodiment] In order to enable your review, the preferred embodiment is described as follows: Bottom: Technical contents of Luming 'Special Excerpt - Embodiment: 5 10 15 In this embodiment, 'the invention reduces the method By using one; * $ ρ + 卜 I, and the power consumption of the 9 horses, the system is used to prepare the system for each work room, ', and the application. The weekly work of the servant will trigger the time and the least common multiple of the competition cycle. 々“Save to the memory of a traditional portable device. When the money _ #,# triggers (4), the ii{interruption β is requested to perform the appropriate work, and the power of the portable device is interrupted by... - The number of times of 'Wo' is reduced and the background of the background is reduced to achieve the purpose of the present invention. Take the above-mentioned jin and operation application as an example, the work-time, work 2, _^ work cycle is 45 seconds, and the work cycle is executed every 30 seconds every 2 sec. 3 work ^ Ή . Therefore, the cycle time is 180 seconds. In a :: cycle ' at 2〇, 40, 6〇, 8. , 1〇〇, 12〇, and 180 seconds will be executed when the work seconds spleen ^ & 〇 '90, 12 〇, 150, and (10) will perform work 3 privately; will be executed at 45 pm 1M, and 180 seconds Figure 2 does not trigger the time to interrupt the request to perform the appropriate work... Bu is issued interrupt q, #,, non-mother interval, a known time slot time, after the month, 4, the portable device can effectively Reduce the number of standby Ί, , : the general state. The work of the portable device is reduced in accordance with the present invention. The method of 'Shaw consumption' can be implemented in the system without affecting the background work. 13 1312470 No. 93131834 'May 98 revision page to achieve the traditional architecture and the system architecture without changing the traditional portable device The purpose of power consumption. The touch corresponding to the method of power consumption is shown in Fig. 3. The invention reduces the portable method by the following steps: ~ 5 10 15 Step S20: System initialization. Step S22. Acquire the time of each background job and record it. “Step S26 ······························································································· After the end of the system cycle, the time (4) is zero, and in the next system cycle, step S26 is repeatedly executed., ''Step S28: Crust. First Embodiment: Second Embodiment of the Invention It is similar to the first embodiment of the present invention, so it will only be described. As shown in FIG. 4, the method for reducing the power rate loss of the portable device of the present invention includes: Step S30: System initialization. The work cycle corresponding to the application of each background job is recorded and recorded. ^ k S34 . When the work cycle is matched, the application of the work scene is executed. In this embodiment, the invention is reduced. The method of power consumption is to store only the work week of each application of the background work. The work cycle corresponding to the work cycle 开始 The start or end cycle of the work cycle. The background work corresponding to each work cycle of each line Should = break request 'to take step S36: end.
