Field of the Invention The present invention relates to an electronic device, and more particularly to a quick start method of an electronic device. [Prior Art] When the electronic device is normally shut down, the power of all the hardware of the system will be cut off. In this way, the data in the memory of the system will be lost. At the next startup, the electronic device needs to reload the data, resulting in a longer boot time. long. At present, in order to be faster at the next boot, the electronic device generally does not adopt a normal shutdown, but enters a standby state. The electronic device that enters the standby state generally copies the data in the central processing unit into the dynamic random memory, and causes the dynamic random memory to enter the power saving state, and then restores the data to the central processing unit at the next power-on. Since the dynamic random memory in the power-saving state has a small power consumption, generally 8-10 mA, and can greatly increase the booting speed, this technology has been rapidly popularized. However, unpredictable factors such as static electricity and lightning may damage the data stored in the dynamic random memory, causing the electronic device to start up after being turned on again after the % is in the standby state. Therefore, there is a need to provide a system to overcome this potential hazard. SUMMARY OF THE INVENTION In view of the above, it is desirable to provide an electronic device that can be activated even when its startup cannot be completed normally. In addition, a startup method is required to enable the electronic device to be activated even when the quick start cannot be completed normally. 099107553 Form No. A0101 Page 3 of 15 〇992〇13613^〇[0005] 201133339 [0007] [0008] [0008] The electronic device in the embodiment of the present invention includes a micro control unit, non-volatile random access Memory, dynamic random memory and central processing unit. A non-volatile random access memory stores a boot loader for booting the system after the micro control unit receives the boot command. The electronic device further includes an electronic dog, a standby module, a control module and a startup module. The standby module controls the electronic device to enter a standby state after receiving the standby command. The control module starts the electronic dog to start timing within a preset period after the boot loader boot system is started. The boot module quickly starts the electronic device after the boot loader boot system is started, and determines whether the electronic dog has timed out. The control module activates the electronic device in the normal manner if the quick start is not completed but the electronic dog has timed out. The dynamic random memory stores the standby module, the control module, and the startup module, and the central processing unit executes the above modules to realize its functions. The startup method in the embodiment of the present invention is used in an electronic device. Electronic insertion includes a micro control unit, non-volatile random access memory, and an electronic dog. A boot loader is stored in the non-volatile random access memory. The method includes: controlling the electronic device to enter a standby state after receiving the standby command; receiving the startup command by the micro control unit; starting the loading program to start the system; starting the electronic dog to perform timing within a preset period; and quickly starting the electronic device Determining whether the electronic dog has timed out when the quick start electronic device is not completed; and if the quick start is not completed but the electronic dog has timed out, the electronic device is activated in the normal manner. The above and the technical effects of the invention can be easily understood from the following detailed description of the embodiments and the accompanying drawings.

For an electronic device such as a set top box using an infrared remote control, the activation interface 1〇2 can be an infrared receiving end for receiving an infrared remote start command from the outside. Another example is an electronic device such as a personal computer that is activated by a button. The activation interface 102 can be a button for activation and receives an external activation command. The micro-control unit 100 is coupled to the boot interface 102 for controlling the boot interface 102 to detect a boot command. The non-volatile random access memory 11 存储 stores a boot loader 112, which is used to boot the system after the micro control unit 1 侦测 detects an external boot command. The special purpose processor 160 is used to perform specific functions of the electronic device 1, such as video and audio encoding and decoding functions. [0011] In the embodiment, the electronic device 1 further includes a standby module 170, a startup module 172, and a control module 174. The above-mentioned modules 17〇-174 are executable programs stored in the dynamic random memory 130, and their respective functions are completed by the execution of the central processing unit 14,.

[0016] [0016] In step S200, the standby module 170 detects a standby instruction. In step S202, the standby module 170 turns off the special purpose processor 16A. In step S204, the standby module 170 turns off the clock frequency of the central processing unit 14 and stores the standby command originally stored in the dynamic random memory 13A into the buffer 142. In step S206, the standby module 170 writes the temporary storage data 134 in the register of the central processing unit 14 and the current execution position (Pr〇gram Counter) 136 of the command into the dynamic random memory 13A. At this time, the temporary storage data 134 and the execution position 136 are stored in the dynamic random memory 130. After the data in the central processing unit 140 is written into the dynamic internal memory ,3〇, in step S208, the standby module 170 writes an identifier 132 in the dynamic random memory 13A for indicating that the data has been stored at the time of shutdown. The data in the central processing unit 140 can be quickly started at the next power-on. In step S210, the standby module 17 causes the acoustic random memory 13 to enter the Self-refresh Mode. In step S212, the standby module 1 70 turns off the system power supply except the dynamic random memory 丨3〇 and the micro control unit ,, and the electronic device 10 is in the standby state. At this time, only the dynamic random memory 13〇 and the micro control unit 电子 are in the power supply state in the electronic device 10, and the power consumption of the dynamic random memory 130 in the self-updating mode is 35〇 in the normal mode. The mA is reduced to mA, which greatly reduces the system's power consumption. FIG. 3 is a flow chart of the electronic device 1 () in FIG.

If the data such as the temporary storage data 134 and the execution location 136 are damaged, resulting in a failure to start normally, the startup module 172 activates the electronic device 1 in the normal manner in step S305. If the electronic dog 15 has not timed out after the data of the central processing unit 140 is normally restored, indicating that the electronic device 10 has performed a quick start, the control module 174 turns off the electronic dog 150 in step S312, and in step S314. The boot module 172 initializes the special purpose processor 160 to complete the boot. The electronic device 10 and the method for starting the same according to the embodiments of the present invention use the electronic dog 150 to detect whether the quick start of the electronic device 10 is completed on time, so that the electronic device 10 is switched to the dynamic random memory 130 during standby. When the data in the data is damaged, it can be started in the normal startup mode, thereby avoiding the hidden dangers of the quick start and making the quick start more reliable.
