[background technology]
After traditional digital TV set-top box standby; whole standby program is to move in DDR; the clock frequency of CPU does not change yet; and its most peripheral circuit is still in work; how many power consumptions do not have to descend substantially, and are serious to the consumption of the energy after the therefore long-time standby, especially today energy crisis rise from all around; society advocates under the overall situation of energy-saving and emission-reduction, and the user is increasing to having the set-top box demand that possesses true stand-by energy-saving environment-friendly type.
[summary of the invention]
The technical problem to be solved in the present invention, the method that is to provide a kind of set-top box to realize low power consumption and true standby function, the control of power consumption can descend power consumption set-top box when standby by to standby the time, greatly reduces the consumption of the energy, to realize environmental protection.
The present invention is achieved in that a kind of set-top box realizes the method for low power consumption and true standby function, the related standby program of this method is operation among the cache (cache memory) in set-top box CPU, the power consumption control when realizing set-top box standby by this cache.
Power consumption control when described standby program is also closed the further realization of most peripheral circuit to set-top box standby by the clock frequency of reduction CPU and according to certain sequencing.
Described standby program comprises and enters standby program step, operation standby program step and withdraw from the holding state step.
The described standby program step that enters comprises:
Step 11, when the set-top box program is normally moved, whether the main program supervisory user is the standby command input, this standby command input comprises treats the switch input on the power key of remote controller or the panel, if the standby command input is arranged, then set-top box enters standby mode;
Step 12, main program be audio frequency and video module, demultiplexing module, the OSD display module of closure plane top box one by one, and all GPIO output;
Step 13, main program begin the cache of CPU is configured, and simultaneously the standby program are copied among the cache, and jump to the standby program that begins among the cache to carry out among the cahce, give the standby that moves program the control of CPU in cache.
Described operation standby program step comprises:
Step 21, set-top box enter into cahce operation standby program, and the power supply of tuner is then cut off in the operation of standby stop SDRAM or DDR-SDRAM and power supply, closes the tuner controller module simultaneously, cuts off the power supply that panel shows again;
Step 22, the clock frequency of regulating CPU are reduced to the lower frequency that set-top-box chip allows with the clock frequency of CPU;
Step 23, begin to wait for and receive the input that the user finishes standby command, comprise and treat the switch input on the power key of remote controller or the panel,, then withdraw from holding state if the input that finishes standby command is arranged.
The described holding state step that withdraws from comprises:
Step 31, at first recover power supply, simultaneously it is reconfigured, make it can operate as normal SDRAM or DDR-SDRAM;
Step 32, then recover power supply, simultaneously tuner is reconfigured startup tuner;
Step 33, start the power supply that panel shows then;
Step 34, restart audio frequency and video module and demultiplexing module;
Step 35, open the output function of all GPIO;
Step 36, at last the clock frequency of CPU is adjusted to original frequency;
Step 37, main program is loaded into SDRAM or the DDR-SDRAM from flash again, and jumps to SDRAM or DDR-SDRAM goes up the operation main program, the control of CPU is returned main program;
Step 38, finish the standby process, enter normal running state of programs with regard to this set-top box.
The present invention has following advantage: utilize the cache of set-top box CPU to carry out the operation of standby program, after entering standby mode, regulate the clock frequency of CPU, be reduced to the lower frequency that chip allows, close relevant power consumption parts when the standby by peripheral circuit, realized when standby, make it when standby the best and power consumption can be dropped to about 10% of mode of operation at ordinary times the control of power consumption, greatly reduce the consumption of the energy, really realize environmental protection.Thereby the merit power consumption is big when having solved traditional digital TV set-top box standby, can't realize the problem of purpose of energy saving.
