More than be the concrete structure of self-refresh control module 4, in the embodiment of the present application, use this circuit structure only to be used for description and interpretation the application, and be not used in restriction the application, in actual applications, the user can select different self-refresh control modules 4 to replace, and the application does not limit.
In the embodiment of the present application, data are stored among the RAM1 by starting shooting, replace the prior art data of will starting shooting to be stored in technical scheme among the ROM, and the browsing data that uses electronic equipment to keep electronic equipment user before standby also is stored among the RAM1.
Its main workflow is as follows:
Electronic equipment is from the normal condition to the holding state:
At first, after CPU3 receives " standby " order, the data of CPU3 and electronic equipment start can be stored among the RAM1.
Then, CPU3 sends " voltage enable signal " to voltage management module 2, and control voltage management module 2 is the RAM1 power supply when electronic equipment is in holding state, and after the system of remaining on entered " standby " state, the data among the RAM1 were not lost.
Secondly, CPU3 sends the self-refresh enable signal " to self-refresh control module 4; control self-refresh control module 4 sends the self-refresh control signals to RAM1; it is the first browsing data that the second browsing data is refreshed, the up-to-date browsing data that makes RAM1 can keep electronic equipment user before standby to use electronic equipment to keep.
In the embodiment of the present application, " voltage enable signal " and " self-refresh enable signal " all is that the GPIO mouth of CPU3 provides.
Again, most of power supply that system in the electronic equipment is cut off in CUP control, except RAM1 keeps electric weight, most of subsystem is de-energized in the whole system, therefore complete machine enters " standby (or dormancy) " state, and electronic equipment then only needs to consume lower power consumption, and, CPU3 can only respond " start " order, and other any orders can not respond without exception.
Electronic equipment is from the holding state to the open state:
At first, CPU3 receives starting-up signal.
Secondly, send the voltage enable signal to voltage management module 2, the power supply that control voltage management module 2 needs when providing start for electronic equipment.
Again, opening whole system power supplies is to be the system power supply in the electronic equipment.
Again, after all subsystems entered steady-working state, CPU3 directly extracted start Data Control electronic equipment and is adjusted into open state from holding state from RAM1.
Because CPU3 directly reads the start data from RAM1, compare with reading information from ROM, the speed of reading information is faster from RAM1, and because the start data intactly have been present among the RAM1, CPU3 does not need to carry out the operation of " reloading operating system " again, and then " standby " front breakpoint trouble-free operation is gone down, therefore, can greatly shorten the available machine time, it is very good that the user experiences.
In addition, after electronic equipment is in open state, CPU3 can extract the first browsing data from RAM1, and after the electronic equipment start, load the first browsing data, to keep all front states of " standby ", comprise the picture that the moment before the standby shows at electronic equipment screen, the user is experienced be greatly improved.
Following illustrative examples describes:
Adopt the electronic equipment of the boot-strap circuit of the present invention's proposition, the user starts the network function of electronic equipment, in the process of browsing " webpage ", presses " standby " key on the remote controller, and complete machine enters " standby " state immediately.After the user again presses " standby " key on the remote controller and sends " start " order, the television boot-strap process is very fast, and what directly present to the user after the start is exactly the webpage of " standby " front browsing, and the user can continue to browse, and not needing takes time again resets and search for.
Therefore, " quick turn-on system " that adopts the present invention to propose, it is very good that the user experiences;
In the above-described embodiments, a kind of boot-strap circuit and starting-up method have been described, data are stored among the RAM by starting shooting, replace the prior art data of will starting shooting to be stored in technical scheme among the ROM, when electronic equipment is started shooting, can directly from RAM, call the start data, shorten the available machine time, and, the browsing data that uses electronic equipment to keep electronic equipment user before standby also is stored among the RAM, electronic equipment is after entering open state, and the up-to-date browsing data of rear loading of can also starting shooting makes the electronic equipment start just can recover mode of operation before afterwards.
Further, before standby, refresh browsing data by the self-refresh control module at electronic equipment, and send to RAM, can make electronic equipment after start, return to fast former browse state.
Embodiment two:
In the embodiment of the present application, provide a kind of TV, having comprised:
At least one functional circuit.
Boot-strap circuit and is connected functional circuit and is connected, and comprises the boot-strap circuit of describing such as above-mentioned embodiment.
Electric supply installation is connected with boot-strap circuit, is used to the power supply of at least one functional circuit and boot-strap circuit.
By one or more embodiment of the present invention, can be achieved as follows technique effect:
In above-mentioned one or more embodiment, a kind of boot-strap circuit and starting-up method have been described, data are stored among the RAM by starting shooting, replace the prior art data of will starting shooting to be stored in technical scheme among the ROM, when electronic equipment is started shooting, can directly from RAM, call the start data, shorten the available machine time, and, the browsing data that uses electronic equipment to keep electronic equipment user before standby also is stored among the RAM, electronic equipment is after entering open state, and the up-to-date browsing data of rear loading of can also starting shooting makes the electronic equipment start just can recover mode of operation before afterwards.
Further, before standby, refresh browsing data by the self-refresh control module at electronic equipment, and send to RAM, can make electronic equipment after start, return to fast former browse state.
Obviously, those skilled in the art can carry out various changes and modification to the present invention and not break away from the spirit and scope of the present invention.Like this, if of the present invention these are revised and modification belongs within the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and modification interior.
