Patent ID: 8886968

Claim:
A method for controlling a dual-processor switch, applicable to a terminal having a processor system and an embedded processor system, the terminal including a switch module coupled to the processor system and the embedded processor system, the switch module being coupled to a peripheral device of the terminal, the method comprising: receiving a triggering signal by the switch module for switching to the embedded processor system, when the switch module is controlling the peripheral device by receiving a control signal from the processor system; waking a the embedded processor system by the switch module, and switching to receive a control signal sent from the embedded processor system; and controlling the peripheral device by using the control signal from the embedded processor system, wherein, (1) the switch module comprises: (i) a display switch unit coupled to a display module, (ii) a USB signal switch unit coupled to a USB peripheral device, (iii) a storage sharing switch unit coupled to a FLASH or a memory card interface, and (iv) an audio signal switch unit coupled to an audio device, and (2) the switch module receiving the triggering signal to switch to the embedded processor system comprises: (i) when a switch button on the terminal is pressed, the switch module receiving the triggering signal to switch to the embedded processor system, which corresponds to the switch button, (ii) when the processor system is in a sleep state or a standby state, the switch module receiving the triggering signal to control the peripheral device through the embedded processor system, (iii) when the power level of the terminal is lower than a threshold value, the switch module receiving the triggering signal to switch to the embedded processor system, and (iv) when the terminal starts up a specific application software, the switch module receiving the triggering signal to switch to the embedded processor system.
