Description of the invention (1) [Technical field to which Faming belongs] • The present invention relates to a power management technology, especially a portable electronic device, so that it can reduce consumption during operation Power method. ['Pre-Technology] With the maturity of computer and electronic technology, it has prompted portable electronic devices such as personal digital assistants (PDAs), MP3 (MPEG Layer3) players, notebook computers (Note Bo ok), and electronic dictionaries. It is developing rapidly and is becoming more and more popular. Because of this, each product manufacturer has invested a considerable amount of effort in product research and development and improvement, and it is expected to launch a specification model that meets market demand in order to compete fiercely and change trends. Achieved a leading edge in the sales market channel. The current market demand trend and the projects in which various manufacturers actively invest in research and development costs are whether it is possible to extend the standby and operating time of the product, and because portable electronic devices launched on the market today must have "action π (Μ〇) bi 1 e) features, in order to have a place in the consumer market, such as the words of action language, mobile video, mobile office, etc., almost have become the terms used by various manufacturers in product marketing packaging, The trend of mobile products with portable products has been favored by consumers. _ At present, portable electronic devices, such as digital cameras, personal digital assistants, handheld TVs, and electronic dictionaries, are generally the largest in the consumer market. In addition to whether the volume can be reduced, another problem is the issue of power consumption. Since it is advertised as mobile, it also means that it is not always possible to transmit mains power through wires to provide power. Therefore, various types of batteries have been used to replace the mains. Pair portable

第12頁 200411368 五、發明說明（ίο) 影作業，若已完成，遂將硬碟2 0及聲音解碼器1 5之電源予 以關閉後，返回步驟（2 0 )重新進行功能選擇。^ 綜合上述可知，當中央處理單元5於接收到使用者所 選擇之工作指令後，中央處理單元5隨即對執行此一工作 指令所需之功能模組及操作流程進行控制與安排，以於執 行該項工作指令時，可對多媒體播放器1進行電源管理作 業，中央處理單元5係將於執行該項工作指令過程中，將 已動作完畢，暫時無須使用之功能模組予以關閉，俟如需 用到時方又將其之電源重新開啟，藉以減少多媒體播放器 1於執行各項工作指令時所需消耗之電力，以延長多媒體 播放器1之操作時間及電池之使用壽命。 以上所述僅為本發明之較佳實施例而已，並非用以限 定本發明之實質技術内容之範圍。本發明之實質技術内容 係廣義.地定義於下述之申請專利範圍中，任何他人所完成 之技術實體或方法，與下述之申請專利範圍所定義者完全 相同，或是為同一等效之變更，均將被視為涵蓋於此專利 範圍之中。Page 12 200411368 V. Description of the invention (ίο) If the video operation has been completed, turn off the power of hard disk 20 and sound decoder 15, and then return to step (20) to perform function selection again. ^ Based on the above, it can be known that when the central processing unit 5 receives the work instruction selected by the user, the central processing unit 5 then controls and arranges the functional modules and operation processes required to execute this work instruction for execution. During this work order, the power management operation of the multimedia player 1 can be performed. The central processing unit 5 will shut down the function modules that have been completed during the execution of this work order and need not be used temporarily. When necessary, turn on the power again to reduce the power consumed by the multimedia player 1 when executing various work instructions, so as to extend the operating time of the multimedia player 1 and the service life of the battery. The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the essential technical content of the present invention. The essential technical content of the present invention is broadly defined in the scope of the following patent applications. Any technical entity or method completed by others is exactly the same as that defined in the scope of the patent applications described below, or is the same equivalent. Changes are deemed to be covered by this patent.
