Problems solved by technology

[0003] At present, there are some power-saving methods for portable electronic devices in the public technology, such as setting a standby state or a sleep state for the electronic device, but when the electronic device is in the standby state or sleep state, non-volatile devices such as flash memory hard disks for long-term data storage The memory is still powered, so that the electronic device cannot further save power, so there is a need for a power saving method that can further save power consumption

Embodiment Construction

[0011] Please refer to FIG. 1 , which is a structural diagram of a portable electronic device with power saving function. The device includes: a first memory 11 , a second memory 12 , a power control unit 13 , a power supply 14 , a central processing unit 15 and a timer 16 . The first memory 11 is a non-volatile memory, which can save the data therein for a long time even in the case of power failure, such as magnetic storage media, flash memory (Flash Memory), etc., and the first memory 11 is used to store the portable data in electronic devices. The second memory 12 is a volatile memory, that is, in the case of power failure, the data stored therein will be lost, but because of its fast access speed, it is generally used as a memory, such as RAM, DRAM, etc. The memory 12 is used as the internal memory of the portable electronic device, and stores the data read from the first memory 11 for processing by the central processing unit 15, and can temporarily store the data obtai...

Abstract

This invention provides one portable electron device and its method with electricity save function, which comprises the following steps: providing one portable electron device composed of one first memory, one second memory, one power, one CPU and one power control unit; receiving one operation order; sending one start order to the control unit; the control unit establishes first memory according to start order; reading the first memory data into second one; sending one close order to the control unit; the power control unit breaks connection between first memory and power according to the close order.

Description

【Technical field】 [0001] The invention relates to a portable electronic device with power saving function and its realization method. 【Background technique】 [0002] With the development of electronic technology, various portable electronic devices such as mobile phones, PDAs, e-books, etc. have brought great convenience to people's daily work, study and entertainment. , The power of the battery is gradually consumed during use, causing it to be turned off. Therefore, prolonging the use time of the battery is a major demand for portable electronic devices. Generally, there are two ways to prolong the usage time of the electronic device, one is to prolong the usage time of the battery, and the other is to reduce the power consumption of each component as much as possible. [0003] At present, there are some power-saving methods for portable electronic devices in the public technology, such as setting a standby state or a sleep state for the electronic device, but when the el...
