In an embodiment of the present invention, referring to FIG. 2, the first processor 10 and the second processor 20 perform state communication through four sets of GPIOs (references 1-4), wherein the states include: a sleep state and an awake state. specific:

(1) The first group of GPIOs are used to indicate the sleep or awake state of the first processor 10. When the first processor 10 is in sleep, the first group of GPIO levels are pulled high (or pulled low), and when waking up, the first group of GPIO levels are pulled low (or pulled high). Thereby, the second processor 20 can determine the state of the first processor 10 by reading the level state of the first group of GPIOs.

(2) The second group GPIO is used to indicate the sleep or wake state of the second processor 20. When the second processor 20 is in sleep, the second group of GPIO levels are pulled high (or pulled low), and when waking up, the second group of GPIO levels are pulled low (or pulled high). Thereby, the first processor 10 can determine the state of the second processor 20 by reading the level state of the second group GPIO.

(3) The third group of GPIOs is used to wake up the second processor 20 (the first processor 10 triggers the second processor 20 to wake up). The GPIO on the second processor 20 side has a wake-up interrupt function, that is, when the second processor 20 is in the sleep state, if the third group GPIO generates a falling edge (may also be other states, for example, a rising edge, etc.), The second processor 20 interrupts the sleep state and is woken up.

(4) The fourth group of GPIOs is used to wake up the first processor 10 (the second processor 20 wakes up the first processor 10). The first processor 10 side GPIO has an interrupt wake-up function, that is, when the first processor 10 is in the sleep state, if the fourth group GPIO generates a falling edge (may also be other states, for example, generating a rising edge, etc.), the first The processor 10 is awakened by interrupting the sleep state.

Referring to Figure 1, the interface labeled 5 is the USB interface. Referring to Figure 3, an implementation of the present invention In an example, the data and control path connections between the first processor 10 and the second processor 20 are implemented via USB. When the first processor 10 and the second processor 20 perform data communication, the USB interface adopts a host role mode. In the embodiment of the present invention, the first processor 10 acts as a host, and the second process The device 20 acts as a device.

In one embodiment, the VBUS pin (power pin) of the first processor 10 outputs an active high level (eg, 5.0V) to the VBUS pin (power pin) of the second processor 20. After the VBUS pin of the second processor 20 is powered on, the level of the D+/D- pin (data pin) changes. After the first processor 10 detects the change, it considers that a USB device is inserted and initiated. The enumeration process, the two establish a USB connection. Since the USB bottom layer holds the lock, the first processor 10 and the second processor 20 cannot sleep, and if either party needs to sleep, the USB connection needs to be disconnected. Specifically, when the USB connection is disconnected, the VBUS pin of the first processor 10 outputs a low level, so that the VBUS pin of the second processor 20 cannot be powered, and the first processor 10 and the second processor 20 The USB connection between them is broken.

Referring to FIG. 4, a flow chart of the operation states of the first processor 10 and the second processor 20 is shown. When the first processor 10 has an event to interact with the second processor 20, controlling the third group of GPIO controls triggers the second processor 20 to interrupt the falling edge, causing the second processor 20 to exit the sleep mode, ie, the second processor 20 Was awakened. The first processor 10 switches to the host mode, and a USB connection is established between the first processor 10 and the second processor 20. The first processor 10 supplies power to the USB of the second processor 20. When the second processor 20 wakes up, the level of the second group GPIO is controlled to be pulled low, whereby the first processor 10 can learn the wakeup of the second processor 20.

In an embodiment of the present invention, when the second processor 20 needs to perform sleep after the event interaction between the first processor 10 and the second processor 20 is completed, the first processor 10 is disconnected from the second process. The USB connection of the device 20 ensures that the second processor 20 can sleep normally. Specifically, the VBUS pin of the first processor 10 outputs a low level, and the first processor 10 controls the third group of GPIOs to generate a rising edge, triggers the second processor 20 to interrupt the entry, and the second processor 20 enters the sleep state. When the second processor 20 enters When going to sleep, the level of the second group of GPIOs is pulled high, whereby the first processor 10 can know the sleep of the second processor 20.

Referring to FIG. 5, when the second processor 20 needs to wake up the first processor 10 (for example, generating a modem network event, a kernel module of the second processor 20 or other application needs to wake up the first processor 10, etc.), the control The state of the four groups of GPIOs wakes up the first processor 10. After the first processor 10 is woken up, a USB connection with the second processor 20 is established. When the first processor 10 wakes up, the level of the first group of GPIOs is controlled to be pulled low, whereby the second processor 20 can learn the wakeup of the first processor 10.

After the event interaction between the second processor 20 and the first processor 10 is completed, the first processor 10 actively disconnects the USB connection with the second processor 20, enabling the second processor 20 to autonomously sleep. It does not limit the sleep due to the USB connection.

In the embodiment of the present invention, the first processor 10 and the second processor 20 need to first determine the sleep state of the other party when performing the sleep and wake-up operations, and then make a choice whether to wake up the other party, and only perform mutual interaction when necessary. Wake up to minimize system power consumption.

In an embodiment of the invention, when the second processor 20 is powered off, the GPIO and the interrupt are released. Shutdown here refers to the shutdown of the user equipment.

In some embodiments of the present invention, events that interact between the first processor 10 and the second processor 20 include: network events (eg, data traffic through the first processor 10, data through the second processor 20) Business, etc.), events generated by the processor kernel module, events generated by the application, and so on.

In some embodiments of the present invention, the manner in which the first processor 10 and the second processor 20 sleep may include maintaining a low clock or not being powered at all, etc., to save power. The manner in which the first processor 10 and the second processor 20 are awakened includes: being fully powered, etc.

In the embodiment of the present invention, when the first processor sleeps, the USB connection is disconnected, and when the second processor autonomously sleeps, the second processor 20 has active events (eg, control events, network data events, etc.), and actively wakes up. The first processor 10 performs USB reconnection to ensure the side of the second processor 20 The event is transmitted to the first processor 10 in real time; when the event processing is completed, the first processor 10 is notified to disconnect the USB connection, so that the system sleeps, saving power consumption. When the first processor 10 has a request event to the second processor 20, the USB reconnection is actively triggered, and the USB connection is actively disconnected after the event processing is completed to ensure normal sleep of the system and save power consumption.

Referring to FIG. 6, in another embodiment of the present invention, the USB interface of the first processor 10 is used not only for communicating with the second processor 20 but also for communicating with an external device (eg, an OTG device). Therefore, in this embodiment, the USB of the first processor 10 needs to switch the working mode in different scenarios. When the system can enter the sleep mode, the mode needs to be set to mode 2 (NONE mode), and when waking up, it needs to be awake according to The event is set to mode 1 (host mode).

In the above embodiment, the USB path of the first processor 10 is only used to communicate with the second processor 20. Therefore, the USB of the first processor 10 only needs to switch between the host and the none mode.

In this embodiment, the USB path of the first processor 10 is required to communicate with an external device, and the USB of the first processor 10 needs to be in three modes, namely mode 1 (host mode) and mode 2 (none mode). Switching between and , thereby ensuring that it can communicate with both the external device and the second processor. Mode 3 (peripheral mode) is used to communicate with external devices.

Referring to FIG. 6, when the first processor 10 or the second processor 20 enters sleep, the USB of the first processor 10 is switched from mode 1 to mode 2. When the first processor 10 or the second processor 20 exits sleep, the USB of the second processor 20 is switched from mode 2 to mode 1. It should be understood that, in this embodiment, the implementation details of the sleep and wake-up are the same as those of the embodiment shown in FIG. 1 in the switching process between the mode 1 and the mode 2, and details are not described herein again.

Referring to FIG. 6, when an external device (for example, an external computer) is connected to wake up the first processor 10, the USB of the first processor 10 is switched from mode 2 to mode 3. When the connection with the external computer is disconnected, the USB of the first processor 10 is switched from mode 3 to mode 1. When the first processor 10 communicates with the second processor 20, an external computer is connected, and the USB mode of the first processor 10 is switched from mode 1 to mode 3. This is because, when communicating with an external computer, the user device 100 operates in the device mode, therefore, There will be a mode 1 to mode 3 conversion. When the first processor 10 communicates with the second processor 20, the external OTG device is connected, and the first processor 10 maintains mode 1, that is, the USB of the first processor 10 operates in the host mode. The first processor 10 remains in mode 1 when the connection to the external OTG device is disconnected.

In this embodiment of the present invention, the USB of the first processor 10 has a function of communicating with the second processor 20 and an external device, and realizes multiplexing of the USB interface; and only one USB state switching method for the first processor 10 To ensure a balance between power consumption and functionality.

Referring to FIG. 7, the embodiment of the present invention is different from the embodiment shown in FIG. 1 in that, in this embodiment, the first processor 10 includes a first modem processor 101 and a first application processor 102; The second processor 20 includes a second modem processor 201 and a second application processor 202.

The first application processor 102 processes complex logical operations and performs task assignment, provides an interactive interface for the user, and transmits the operation instructions input by the user to the second application processor 202. The first application processor 102 is also configured to execute an operating system of the user device 100. The first modem processor 101 performs protocol processing and modulates and demodulates the transmitted and received communication data to implement communication with an external communication device or the like.

In an embodiment of the present invention, the second application processor 202 does not perform data processing, but only functions as a transparent transmission. For example, the data processed by the second modem processor 201 is transparently transmitted to the first application processor 102 for processing, and the data transmitted by the first application processor 102 is transparently transmitted to the second modem processor 201.

In an embodiment of the present invention, referring to FIG. 7, the first application processor 102 and the second application processor 202 perform state communication through four sets of GPIOs (numbers 1-4) and data through the USB interface (reference numeral 5). transmission. specific:

(1) The first group of GPIOs are used to indicate the sleep or wake state of the first application processor 102. When the first application processor 102 is in sleep, the first group of GPIO levels are pulled high (or pulled low), and when waking up, the first group of GPIO levels are pulled low (or pulled high). Thus, the second application processor 202 reads the first group of GPIOs by reading The level state can determine the state of the first application processor 102.

(2) The second group of GPIOs is used to indicate the sleep or wake state of the second application processor 202. When the second application processor 202 is in sleep, the second group of GPIO levels are pulled high (or pulled low), and when waking up, the second group of GPIO levels are pulled low (or pulled high). Thus, the first application processor 102 can determine the state of the second application processor 202 by reading the level state of the second group of GPIOs.

(3) The third group of GPIOs is used to wake up the second application processor 202 (the first application processor 102 triggers the second application processor 202 to wake up). The GPIO on the second application processor 202 side has a wake-up interrupt function, that is, when the second application processor 202 is in the sleep state, if the third group of GPIOs generates a falling edge (other states may also be generated, for example, a rising edge is generated, etc.) The second application processor 202 interrupts the sleep state and is woken up.

(4) The fourth group of GPIOs is used to wake up the first application processor 102 (the second application processor 202 wakes up the first application processor 102). The first application processor 102 side GPIO has an interrupt wake-up function, that is, when the first application processor 102 is in a sleep state, if the fourth group of GPIOs generates a falling edge (other states, for example, a rising edge, etc.), The first application processor 102 is awakened by interrupting the sleep state.

When the first application processor 102 and the second application processor 202 perform data communication, the USB interface adopts a host role mode. In the embodiment of the present invention, the first application processor 102 functions as a host. The second application processor 202 acts as a device.

In one embodiment, the VBUS pin (power pin) of the first application processor 102 outputs an active high level (eg, 5.0V) to the VBUS pin (power pin) of the second application processor 202. After the VBUS pin of the second application processor 202 is powered on, the level of the D+/D- pin (data pin) changes. After the first application processor 102 detects the change, the USB device is considered to be inserted. , initiate the enumeration process, the two establish a USB connection. Since the USB bottom layer holds the lock, the first application processor 102 and the second application processor 202 cannot perform hibernation, and if either party needs to sleep, the USB connection needs to be disconnected. Specifically, when the USB connection is disconnected, the first application processor 102 The VBUS pin outputs a low level such that the VBUS pin of the second application processor 202 cannot be powered up and the USB connection between the first application processor 102 and the second application processor 202 is broken.

In the embodiment of the present invention, the flow of the working states of the first application processor 102 and the second application processor 202 is the same as the flow between the first processor 10 and the second processor 20 shown in FIG. 4 and FIG. 5. When the first application processor 102 has an event to interact with the second application processor 202, controlling the third group of GPIO controls triggers the second application processor 202 to interrupt the falling edge, causing the second application processor 202 to exit the sleep mode, ie, The second application processor 202 is woken up. The first application processor 102 switches to the host mode, and a USB connection is established between the first application processor 102 and the second application processor 202. The first application processor 102 supplies power to the USB of the second application processor 202. When the second application processor 202 wakes up, the level of the second group of GPIOs is controlled to be pulled down, whereby the first application processor 102 can learn the wakeup of the second application processor 202.

In an embodiment of the present invention, when the second application processor 202 needs to perform sleep after the event interaction between the first application processor 102 and the second application processor 202 is completed, the first application processor 102 is disconnected. The USB connection with the second application processor 202 ensures that the second application processor 202 can sleep normally. Specifically, the VBUS pin of the first application processor 102 outputs a low level, and the first application processor 102 controls the third group of GPIOs to generate a rising edge, triggering the second application processor 202 to interrupt the entry, and the second application processor 202 Go to sleep. When the second application processor 202 enters sleep, the level of the second group of GPIOs is pulled high, whereby the first application processor 102 can learn the sleep of the second application processor 202.

When the second application processor 202 needs to wake up the first application processor 102 (eg, when a modem network event is generated, a kernel module of the second application processor 202 or other application needs to wake up the first application processor 102, etc.), the control The state of the four groups of GPIOs wakes up the first application processor 102. After the first application processor 102 is woken up, a USB connection with the second application processor 202 is established. When the first application processor 102 wakes up, the level of the first group of GPIOs is controlled to be pulled down, whereby the second application processor 202 can learn the wakeup of the first application processor 102.

After the event interaction between the second application processor 202 and the first application processor 102 is completed, the first application processor 102 actively disconnects the USB connection with the second application processor 202 to enable the second application processor 202. Can sleep autonomously, without restricting the sleep due to the USB connection.

Specifically, when the user equipment 100 is powered on, the second application processor 202 starts a monitoring process (eg, a WPS task), according to a status event of the first application processor 102 (can be learned by querying the level status of the first group of GPIOs) The monitoring process sets the node to enable the second application processor 202 to enter the sleep autonomously.

When the first application processor 102 has an event (eg, a network event) that needs to interact with the second application processor 202, sending a message to the preset USB monitoring process, and the USB monitoring process controls the third group of GPIO controls to trigger the second application processing. The device 202 interrupts the falling edge. The monitoring process of the second application processor 202 detects an interrupt event, invokes a preset interface (eg, a resume interface), and causes the second application processor 202 to exit the sleep mode, that is, the second application processor 202 is woken up. The USB interfaces of the first application processor 102 and the second application processor 202 remain connected and power the USB of the second application processor 202.

After the event interaction of the first application processor 102 and the second application processor 202 is completed, the USB monitoring process of the first application processor 102 controls the third group of GPIOs to generate a rising edge, triggering the second application processor 202 to interrupt the entry. The monitoring process of the second application processor 202 receives an interrupt event, triggering the second application processor 202 to go to sleep. When the second application processor 202 sleeps, the level of the second group of GPIOs is controlled to be pulled high.

When the second application processor 202 has an event (eg, generating a modem network event) that needs to interact with the first application processor 102, the state of the fourth group of GPIOs is controlled to wake up the first application processor 102. After the first application processor 102 is woken up, the USB port is reconnected. The first application processor 102 queries the detailed event through the control interface, and continues to report to the relevant program of the application layer as needed, and the related program holds the lock until the event processing is completed.

In an embodiment of the present invention, when the first application processor 102 is asleep, the first modem is The processor 101 can be in a sleep or awake state. When the second application processor 202 is asleep, the second modem processor 201 enters a sleep state. In some embodiments, when in a sleep state, the associated device can remain low clocked or not powered at all to save power.

In the embodiment of the present invention, the first application processor 102 and the second application processor 202 need to first determine the sleep state of the other party when performing the sleep and wake operation, and then make a choice whether to wake up the other party, and only if necessary Wake up each other to minimize system power consumption.

In an embodiment of the invention, when the second application processor 202 is shut down, the GPIO and the interrupt are released. Shutdown here refers to the shutdown of the user equipment.

It should be understood that the USB switching scheme of the embodiment shown in FIG. 6 above is equally applicable to the first application processor and the second application processor of the embodiment. That is, when the USB of the first application processor in the implementation has the function of communicating with the second application processor 202 and the external device, the first application processor 102 can adopt the USB of the embodiment shown in FIG. 6 above. State switching method to ensure power and function balance.

In an embodiment of the present invention, the first application processor disconnects the USB connection while sleeping, enabling the second application processor to autonomously sleep; the second application processor 202 has active events (eg, control events, network data events, etc.) At this time, the first application processor 102 is actively woken up to perform USB reconnection. The event on the second application processor 202 side is ensured to be transmitted to the first application processor 102 in real time; when the event processing is completed, the first application processor 102 is notified to disconnect the USB connection, so that the system sleeps, and power consumption is saved. When the first application processor 102 has requested the event to the second application processor 202, the USB reconnection is actively triggered, and the USB connection is actively disconnected after the event processing is completed to ensure normal sleep of the system and save power consumption.
