The electronic device may be a smart phone, a smart watch, a tablet computer, or the like, or may be a game device, an AR (Augmented Reality) device, an automobile device, a data storage device, an audio playing device, a video playing device, a notebook computer, a desktop computing device, or the like, or may be a wearable electronic device such as an electronic helmet, electronic glasses, electronic clothing, or the like.
Referring to fig. 1, fig. 1 is a first structural schematic diagram of an electronic device 100 according to an embodiment of the present disclosure.
The electronic device 100 includes a main processing chip 10 and a co-processing chip 20. The co-processing chip 20 is electrically connected to the main processing chip 10. It will be appreciated that an electrical connection may be a direct connection to enable transfer of electrical signals, or an indirect connection, such as through a switch or other electronic device to enable transfer of electrical signals.
The main processing Chip 10 may serve as a main control SOC (System on Chip) of the electronic device 100. The main processing chip 10 may have integrated thereon a processor and a memory, such as a first processor which may perform data processing and a first memory which may store data, including a first operating system and an application program. The main processing chip 10 may run a first operating system and applications.
The co-processing chip 20 is a low power SOC. The operating power consumption of the co-processing chip 20 is less than the operating power consumption of the main processing chip 10. The co-processing chip 20 may also have integrated thereon a processor and a memory, such as a second processor that may perform data processing and a second memory that may store data, including a second operating system and application programs. The co-processing chip 20 may run a second operating system and applications.
When the electronic device is in the screen-off mode or in the screen-off display mode, the main processing chip 10 enters the sleep state. When the main processing chip 10 is in the sleep state, the co-processing chip 20 may receive a voice signal transmitted from an external component, such as a Microphone (MIC), and detect the voice signal. When detecting that the voice signal contains the preset awakening word, awakening the main processing chip 10, so that the main processing chip 10 is switched from the dormant state to the working state to perform task processing. For example, the main processing chip 10 acquires voice data after being awakened, and performs voice processing based on the voice data.
Because the operation power consumption of the co-processing chip 20 is less than that of the main processing chip 10, the co-processing chip 20 based on low power consumption detects the voice signal, and only when the preset wake-up word is detected, the main processing chip 10 can be woken up, so that the main processing chip 10 with high power consumption can be prevented from being woken up for many times, the whole power consumption of the electronic equipment can be effectively reduced, and the endurance time of the electronic equipment is further prolonged.
Referring to fig. 2, fig. 2 is a first structural diagram of a co-processing chip 20 of an electronic device 100 according to an embodiment of the present disclosure. The co-processing chip 20 includes a voice processing module 21. The voice processing module 21 is used for performing audio data processing. The voice processing module 21 may be configured to extract keywords from the audio data, and determine whether the provided keywords include a preset wake-up word.
In a possible embodiment, voiceprint recognition may also be performed by the speech processing module 21, so that the voice control of the user is authenticated by the voiceprint recognition result of the speech processing module 21. The processing frequency of the voice processing module 21 can reach 400MHz, and the voice algorithm can be processed more efficiently.
Referring to fig. 3, fig. 3 is a second structural diagram of a co-processing chip 20 of an electronic device 100 according to an embodiment of the disclosure. The co-processing chip 20 includes a voice processing module 21, a voice detection module 22 electrically connected to the voice processing module 21, and a communication bus 23.
The communication bus 23 is, for example, a NOC (Network on Chip). Wherein, the voice processing module 21 and the voice detecting module 22 can be electrically connected with the communication bus 23 to realize communication between each other.
The voice detection module 22 is a normally open (always) module, which is always in a power-on working state, and no matter the co-processing chip 20 is in a working state or a sleep state, the voice detection module 22 is always in the power-on working state, that is, the voice detection module 22 is not powered off, and always detects the input voice signal. The voice detection module 22 is configured to detect whether the amplitude of the voice signal is greater than a preset amplitude when the voice signal is received; and when detecting that the amplitude of the voice signal is greater than the preset amplitude, waking up the voice processing module 21; the voice processing module 21 is configured to obtain voice data corresponding to the voice signal after being awakened, and detect whether the voice data includes a preset awakening word; and when detecting that the voice data contains the preset awakening words, awakening the main processing chip 10.
Referring to fig. 4, fig. 4 is a schematic diagram illustrating a third structure of a co-processing chip 20 of an electronic device 100 according to an embodiment of the disclosure. The co-processing chip 20 further includes a storage module 24, and the storage module 24 is electrically connected to the voice detection module 22 and the voice processing module 21. The memory module 24 may also be electrically connected to the communication bus 23 to enable communication with other modules.
In some embodiments, the voice detection module 22 is further configured to trigger an interrupt signal to wake up the voice processing module 21 when detecting that the amplitude of the voice signal is greater than the preset amplitude; the voice processing module 21 is further configured to switch the operating mode of the storage module 24 from the exclusive mode to the bus mode and enter the operating state when the interrupt signal is detected. When the memory module 24 is in the exclusive mode, the memory module 24 may receive the stored data of the voice detection module 22, but the voice processing module 21 cannot obtain the voice data from the memory module 24, at this time, the voice processing module 21 only responds to the interrupt signal of the voice detection module 22, and when the memory module 24 is in the bus mode, the voice processing module 21 may obtain the voice data in the memory module 24 for processing.
The voice data stored in the memory module 24 by the voice detection module 22 is not detected until the voice processing module 21 wakes up, and it only responds to an interrupt signal from the voice detection module 22. Once the voice processing module 21 detects the interrupt signal sent by the voice detecting module 22, the memory module 24 can be switched from the exclusive mode to the bus mode by writing the register of the memory module 24. At this time, the voice processing module 21 may obtain the voice data from the storage module 24 to process the voice data, which corresponds to the communication between the voice processing module 21 and the storage module 24 being turned on.
Referring to fig. 5, fig. 5 is a schematic diagram illustrating a fourth structure of a co-processing chip 20 of an electronic device 100 according to an embodiment of the disclosure. The register data in the embodiments of the present application may be stored in a unified manner in another module, for example, in the Register (REG) module 28 shown in fig. 5. The register data of the storage module 24 and the power management module 27 in the following description may be stored in the register module 28, and when other modules need to modify the register data, the corresponding register data in the register module 28 may be accessed and modified through the communication bus 23 to control the corresponding modules to perform corresponding functions.
In some embodiments, the voice detection module 22 is further configured to store the voice data in the storage module 24 when detecting that the amplitude of the voice signal is greater than the preset amplitude; the voice processing module 21 is further configured to retrieve voice data from the storage module 24 after being awakened.
For example, when the voice detection module 22 receives a voice signal and detects whether the amplitude of the voice signal is greater than a preset amplitude, the voice data is stored in the storage module 24 when the amplitude of the voice signal is greater than the preset amplitude. Meanwhile, the voice detection module 22 wakes up the voice processing module 21, and after being woken up, the voice processing module 21 is configured to obtain the voice data from the storage module 24, detect whether the voice data includes a preset wake-up word, and wake up the main processing chip 10 when detecting that the voice data includes the preset wake-up word.
In some possible embodiments, the speech processing module 21 may include a DSP and a WDT 1. The DSP is used to perform voice data detection and the WDT1 is a timer used to instruct the DSP to time out acquiring data. If the DSP detects that the voice data does not contain the preset awakening word, the DSP continues to acquire the voice data from the storage module 24; when the voice data is not acquired from the storage module 24 within the preset time period, the sleep state is entered. If the DSP acquires the voice data from the storage module 24, the DSP controls the time recorded by the WDT1 to return to zero, otherwise, the WDT1 keeps timing, and when the timing reaches a preset duration, triggers a sleep signal, and when the DSP detects the sleep signal, the DSP switches from the working state to the sleep state.
It should be noted that, in a typical electronic device, the DSP for voice processing includes a Memory module (Memory), that is, the Memory module 24 and the DSP are disposed in the same module, that is, the Memory module 24 is typically disposed in the voice processing module 21, and the Memory module 24 is only used for storing voice data, but not used for storing other data. In the co-processing chip 20 of the present application, the storage module 24 is independent, and the storage module 24 can be used for storing not only audio data but also other data, so that the sharing of the storage module 24 can be realized, and the utilization rate of the storage module 24 can be improved.

The co-processing chip 20 further includes a co-processor 25, and a first communication interface module 26 electrically connected to the co-processor 25 and the voice processing module 21.
The voice processing module 21 is further configured to wake up the coprocessor 25 when detecting that the voice data includes a preset wake-up word, so as to start the first communication interface module 26; the voice processing module 21 is further configured to send a wake-up request to the main processing chip 10 through the first communication interface module 26; the main processing chip 10 is further configured to enter a working state when receiving a wake-up request sent by the voice processing module 21.
The coprocessor 25, such as a CPU, is used for controlling the entire coprocessor 20 and performing data operations, such as initializing the coprocessor 20 when the coprocessor 20 starts to operate, performing data operations when the coprocessor 20 operates, and the like. The CPU may be understood as a control core of the co-processing chip 20. The processing frequency of the CPU can reach 300MHz, and the CPU can be used for control and logic processing.
The first communication interface module 26 is used for communicating with the main processing chip 10. The first communication interface module 26 may include an SPISLV interface and an I2CSLV interface, both of which may be used for communicating with the main processing chip 10.
Wherein, the coprocessor 25 and the first communication interface module 26 may belong to the same power domain. When the coprocessor 25 is powered on, the first communication interface module 26 may be activated to implement communication with the main processing chip 10. Wherein, in some embodiments, the co-processing chip 20 further includes a power management module 27 electrically connected to the co-processor 25; the power management module 27 is configured to control power supply to each module in the co-processing chip 20, for example, the voice processing module 21 is further configured to wake up the co-processor 25 by writing a register corresponding to the co-processor 35 in the power management module 27 when it is detected that the voice data includes a preset wake-up word.
Referring to fig. 7, fig. 7 is a sixth structural schematic diagram of a co-processing chip 20 of an electronic device 100 according to an embodiment of the present disclosure. The voice detection module 22 includes a data conversion unit 221 and a voice detection unit 222. The data conversion unit 221 is configured to determine whether the voice signal is an analog signal when the voice signal is received; when the voice signal is an analog signal, the voice signal is converted into a digital signal, and the voice signal after the conversion processing is transmitted to the voice detection unit 222; and, when the voice signal is a digital signal, directly transmitting the digital signal to the voice detection unit 222; the voice detection unit 222 is configured to detect whether the amplitude of the received voice signal is greater than a preset amplitude; and when the amplitude of the voice signal is greater than the preset amplitude, storing the voice data in the storage module 24. The peripheral components may include microphones of different types, different formats of voice signals, some types of microphones transmitting analog signals, and some types of microphones transmitting digital signals.
The data conversion unit 221 may be, for example, a codec adc (code analog-to-Digital Converter). The Voice Detection unit 222 may be, for example, a Voice Activity Detection (VAD) for detecting whether the amplitude of the Voice signal is greater than a preset amplitude, wherein the preset amplitude is a value preset in the electronic device.
Referring to fig. 8, fig. 8 is a schematic diagram illustrating a seventh structure of a co-processing chip 20 of an electronic device 100 according to an embodiment of the disclosure. The main processing chip 10 includes a second communication interface module and a voice data transmission unit. The second communication interface module may include an SPISLV interface and an I2CSLV interface, and both the SPISLV interface and the I2CSLV interface may be used for communicating with the co-processing chip 20. The first communication interface module 26 and the second communication interface module establish a connection through the communication bus 23.
There are various ways for the main processing chip 10 to obtain the voice data, including at least the following three ways:
in the first mode, the main processing chip 10 obtains the voice data from the storage module 24 through the first communication interface module 26 and the second communication interface module. The voice detection module 22 stores data corresponding to the voice signal in the storage module 24.
In the second mode, the main processing chip 10 obtains the voice data from the voice detection module 22 through the voice data transmission unit.
In a third mode, the main processing chip 10 is further configured to obtain, when the first communication interface module 26 is in an idle state, voice data from the storage module 24 through the first communication interface module 26 and the second communication interface module; and, when the first communication interface module 26 is in the occupied state, acquires voice data from the voice detection module 22 through the voice data transmission unit.
In this embodiment, the main processing chip 10 selects different modes to acquire voice data according to the state of the first communication interface module 26. When all the ports of the first communication interface module 26 are used for transmitting other data and are in an occupied state, the voice data is acquired from the voice detection module 22 through the voice data transmission unit. On the contrary, it can be determined that the first communication interface module 26 is in the idle state, and the main processing chip 10 obtains the voice data from the storage module 24 through the first communication interface module 26 and the second communication interface module.
In addition, it can be understood that after the main processing chip 10 wakes up, the voice processing module 21 and the coprocessor 25 in the co-processing chip 20 do not need to perform voice detection and processing, and may enter a sleep state in order to further reduce power consumption. And the voice detection module 22 and the storage module 24 may continue to operate so as to continue to transmit the voice data input by the user to the main processing chip 10. The voice processing module 21 may enter the sleep state through the WDT1, and before entering the sleep state, may send an interrupt signal to the coprocessor 25 to prompt the coprocessor 25 to enter the sleep state. The coprocessor 25 enters a sleep state upon detecting the interrupt signal.
In this embodiment, when the main processing chip 10 wakes up, if data is directly obtained from the voice detection module 22. The voice data may also be stored in the storage module 24 by the voice detection module 22, and then the main processing chip 10 acquires the voice data from the storage module 24.
In some embodiments, the co-processing chip 20 is further configured to perform voiceprint recognition on the voice signal to obtain voiceprint information when detecting that the voice data corresponding to the voice signal includes a preset wake-up word; and awakening the main processing chip 10 when the preset voiceprint information of the voiceprint information domain is judged to be matched.
For example, when the voice processing in the co-processing chip 20 detects that the voice data corresponding to the voice signal contains a preset wake-up word, it performs voiceprint recognition on the voice signal to obtain voiceprint information, matches the voiceprint information with the preset voiceprint information stored in advance, and wakes up the main processing chip 10 when the matching is successful.
In some embodiments, the main processing chip 10 is further configured to determine a data volume of the voice data after entering the working state, and allocate a memory space matched with the data volume for the voice data; and acquiring the voice data, caching the voice data into a memory space, and processing the voice data, such as recognizing a control instruction included in the voice data.
The electronic device provided by the embodiment of the present application is described next by using a specific application scenario. As shown in fig. 8, when the electronic device is in a screen-off state, the main processing chip 10 is in a sleep state, a voice signal input by a user is received by a microphone of the electronic device and transmitted to the voice detection module 22, after the voice detection module 22 receives the voice signal, if the voice signal is detected by the data conversion unit 221 to be an analog signal, the voice signal is converted into a digital signal and transmitted to the voice detection unit 222, the voice detection unit 222 detects whether the amplitude of the voice signal is greater than a preset amplitude, if the amplitude of the voice signal is greater than the preset amplitude, the voice data is stored in the storage module 24, meanwhile, the voice detection module 22 sends an interrupt signal to the voice processing module 21 to wake up the voice processing module 21, after the voice processing module 21 receives the interrupt signal, the sleep state is switched to a working state, and the voice data is obtained from the storage module 24, and detecting whether the voice data contains a preset awakening word by adopting a preset voice recognition algorithm, if so, awakening the coprocessor 25 by the voice processing module 21 through the communication bus 23 to start the first communication interface module 26, and sending an awakening request to the main processing chip 10 through the first communication interface module 26 to awaken the main processing chip 10. After the main processing chip 10 is switched from the sleep state to the working state, the voice data can be read from the storage module 24 of the co-processing chip 20 through the second communication interface module and the first communication interface module 26, and the detection of the wakeup word is performed again. In addition, in a scenario where the user controls the electronic device through the voice instruction, after the user wakes up the electronic device through the wake-up word, the user may further continue to input other voice instructions, and after the main processing chip 10 detects the wake-up word, the main processing chip may further continue to acquire voice data from the co-processing chip 20 and continue to process the voice data.
