A wake-up circuit (300) includes a receiving unit (30) receiving a wake-up signal, a control unit (32), a voltage converter (34), and a processing unit (36). The control unit (32) continuously generating an enable signal for a first predetermined time period when the receiving unit (30) receives the wake-up signal and stopping generating the enable signal after the first predetermined time period. The power supply (100) provides a secondary voltage to the voltage converter (34) when the electronic device (900) is in the standby state, and the voltage converter (34) converts the secondary voltage to a working voltage when the voltage converter (34) receives the enable signal and forgoes generating the working voltage when the voltage converter (34) fails to receive the enable signal. The processing unit (36) is powered by the working voltage to generate the enable signal and output the enable signal to the voltage converter (34), the processing unit (36) further generates a control signal when the processing unit (36) determines that the wake-up signal is a power-on command, the control signal controls the power supply (100) to power the load (200).

The embodiment of the invention provides awakening and hot-plugging methods and equipment based on a high speed inter-chip (HSIC). One method comprises the following steps that: a host computer acquires that external equipment connected with the host computer through an HSIC bus is in an idling state; the host computer is in a dormancy state; the host computer receives an interruption signal sent by the external equipment through a signal line connected with the external equipment; and the host computer is awakened from the dormancy state according to the interruption signal. Awakening and hot-plugging of the host computer and the external equipment are realized based on the HSIC bus, so that the power of the equipment is saved.

The present invention provides a cloud wake-up method and system, a terminal, and a computer-readable storage medium. The cloud wake-up method includes: receiving a wake-up voice input by a user, and transmitting the wake-up voice to the cloud; performing cloud decoding on the wake-up voice to generate a wake-up text; identifying the wake-up text in the wake-up text; and According to the recognition result, a wake-up instruction is given. Through the cloud wake-up method of the present invention, voice recognition can be completed in the cloud, and the smart device can be woken up in the cloud according to the recognized voice. Therefore, under the condition of ensuring the wake-up quality, the resource consumption of the terminal equipment is reduced, and the power consumption is also reduced.

The invention discloses a clockless chip wake-up circuit, a wake-up method, and a chip, including an acquisition circuit and a detection circuit. The acquisition circuit is used to collect input signals to be detected; the detection circuit is used to detect signals to be detected, and generate wake-up according to the signals to be detected. signal, the detection circuit includes a state detection module, a state latch module, and a state recovery module. The state detection module is connected to the acquisition circuit to detect whether there is a signal input to be detected. If there is a signal input to be detected, the state detection module outputs the signal to be detected. The latch module is connected with the state detection module, and generates a wake-up signal according to the signal to be detected. After the wake-up signal is generated, the state recovery module resets the state latch module and the state detection module, and returns to the detection state. By collecting the input signal to be detected, detecting the signal to be detected, and generating a wake-up signal according to the signal to be detected, clockless IO wake-up is realized, power consumption is minimized as much as possible, and circuit reliability is improved.

The invention discloses a MOST network interface circuit and a corresponding MOST network wake-up method, which receives a pulse signal through an independent LIN transceiver and sends it to an external host controller, and the external host controller judges whether the pulse signal is an ECL wake-up signal, If so, generate an enable signal to enable the first power conversion module to supply power to the MOST controller, thereby realizing the ECL wake-up function of the MOST network; that is, the external host controller corresponding to the MOST network slave node is no longer connected to the MOST control The node is powered off synchronously, but remains in the normal power mode. When other networks need to transmit data, the node can also be woken up. Compared with the prior art, the present invention not only ensures that other network data can still be received through the interface circuit in the dormant state of the MOST network, but also avoids the redundant problems of power detection and management functions, and reduces the cost of the ECU.
