Embodiment Construction

[0033] figure 1 is a schematic diagram of the electronic device 100 according to an embodiment of the present invention. Such as figure 1 As shown, the electronic device 100 includes a first storage module 110 , a volatile storage module 120 and a control unit 130 . In this embodiment, the electronic device 100 is realized by a digital video converter box (STB), but those who apply this embodiment should be able to apply the spirit of the embodiment of the present invention to consumer electronic products such as tablet computers and digital cameras.

[0034] In this embodiment, the first storage module 110 is, for example, a flash memory, which is mainly used to store system software that is mainly operated in the electronic device 100 . Therefore, the person applying this embodiment can also implement the first storage module 110 by using a read-only memory. The volatile storage module 120 is implemented by a dynamic random access memory (DRAM) in this embodiment. The co...

Abstract

The invention provides an electronic device rapidly recovering a starting-up state, a control unit and a control method of the electronic device. The electronic device comprises a first storage module, a volatility storage module and a control unit, wherein the volatility storage module comprises at least two data segments. When the electronic device is started, the control unit copies system software to the volatility storage module, the volatility storage module is used for executing the system software to generate universe variable data, and the universe variable data are stored in the first data segment of the volatility storage module temporarily. The control unit backups the universe variable data to the second data segment of the volatility storage module. When the electronic device returns to a normal work mode from a stand-by mode, the control unit enables the first data segment to be covered with the backup universe variable data, and the system software is executed according to the backup universe variable data.

Description

technical field [0001] The present invention relates to a control technology of a communication device, and in particular to an electronic device, a control unit and a control method of the electronic device that can quickly wake up from a standby mode to a normal operation mode to quickly restore the power-on state. Background technique [0002] When consumers purchase electronic products, in addition to hoping that the electronic products themselves have diversified uses, consumers also hope that these electronic products can be started quickly, or that the electronic products can be switched from standby / power saving mode to quickly return to normal operating mode and be used. These electronic products are, for example, a digital video converter box (Set-Top Box; STB), a digital camera, a tablet computer, a smart phone, etc. [0003] Although many electronic products have a standby / power-saving mode to save power, it allows the electronic product to automatically turn of...
