[0052] Hereinafter, embodiments of the present application will be described in more detail with reference to the accompanying drawings. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0053] To address the technical problem that the processor on the current terminal is frequently awakened to collect sensor data, which will increase the power consumption of the processor. This embodiment provides a control device, as Figure 1 shown, the device includes: an interrupt receiving module (INT Controller) 11, a context management module (Context Manager) 12, and a reading module 13.

[0054] The interrupt receiving module 11 is connected to the context management module 12, and the context management module 12 is also connected to the reading module 13.

[0055] The interrupt receiving module 11 is configured to receive interrupt information corresponding to at least one sensor and send it to the context management module 12.

[0056] The at least one sensor may be a sensor working in the terminal. In this embodiment, the terminal may be a smart device such as a smart phone, a tablet computer, a drone, a smart robot, a smart watch, a smart bracelet, etc., and there are many sensors on these terminals. For example, for a smart watch, more than a dozen sensors may be installed on it, and as long as the smart watch is in the on state, there will be sensors working.

[0057] The interrupt information can be a General-Purpose Input / Output Ports (GPIO) interrupt or a Timer interrupt. This interrupt information can be used to wake up the processor to collect sensor data, and in this embodiment, the control device can use the interrupt receiving module 11 to replace the processor to receive this interrupt information.

[0058] The context management module 12 can be used to manage the sensor context. The context management module 12 is configured to obtain the context of the at least one sensor according to the interrupt information sent by the interrupt receiving module 11, and generate a data reading instruction based on the context of the at least one sensor and send it to the reading module 13.

[0059] The reading module 13 can be used to read the sensor data of the sensor. The reading module 13 is configured to read the sensor data of the at least one sensor by executing the data reading instruction and send it to the context management module 12.

[0060] The context management module 12 is also configured to first store the sensor data sent by the reading module 13 in the first cache, and then determine whether to wake up the processor according to the data volume in the first cache, so as to extract the sensor data in the first cache for processing.

[0061] Compared with the current existing technologies, in this embodiment, a control device such as an SSC microprocessor can be used to replace the processor of the terminal to complete the acquisition of sensor data. By uniformly managing all sensors, collecting the data of all sensors and putting them into the cache, and then waking up the processor when the data volume in the cache reaches the set threshold. In this way, on the one hand, there is no need for the processor to collect sensor data, and on the other hand, the number of times the processor is woken up is reduced, so as to achieve the purpose of reducing power consumption.

[0062] In some examples of this embodiment, the control device further includes: a communication module, such as an M33 interface;

[0063] The communication module is connected to the context management module 12; correspondingly, the context management module 12 is further configured to send a notification message to the communication module when the data volume in the first cache is greater than or equal to a first preset threshold (the corresponding threshold can be set in advance according to actual needs); the communication module is configured to wake up the processor to extract the sensor data in the first cache for processing according to the notification message.

[0064] For example, if the sensor data in the first cache is greater than or equal to a certain threshold, the processor can be woken up through the communication module to extract the sensor data (including the sensor data of at least one sensor) in the first cache for processing. In this way, the wake-up of the processor for corresponding processing can be accurately controlled.

[0065] In some examples of this embodiment, the context management module 12 is further configured to store the received sensor data in a second cache corresponding to each sensor respectively, and determine to store the sensor data in the second cache into a first cache when the amount of data in the second cache is greater than or equal to a second preset threshold value (the corresponding threshold value can be set in advance according to actual requirements).

[0066] For example, sensor A corresponds to cache 1, that is, the sensor data of sensor A is first stored in cache 1; sensor B corresponds to cache 2, that is, the sensor data of sensor B is first stored in cache 2; sensor C corresponds to cache 3, that is, the sensor data of sensor C is first stored in cache 3; if the amount of data in cache 1 is greater than or equal to the threshold value x corresponding to this cache 1, then all the sensor data in cache 1 is stored in the first cache. If the amount of data in cache 2 is greater than or equal to the threshold value y corresponding to this cache 2, then all the sensor data in cache 2 is stored in the first cache.

[0067] Through this cache grading mechanism, the storage situation of sensor data can be better controlled, making the stored sensor data more complete and accurate, and thus the accuracy in subsequent data processing by the processor can be improved.

[0068] It should be noted that the control device provided in this embodiment can specifically be an electronic device or a chip of a terminal, etc.

[0069] Further, based on the control device as shown in Figure 1 this embodiment also provides a control method, which can be executed by this control device. As shown in Figure 2 this, this method includes:

[0070] Step 201, receive interruption information corresponding to at least one sensor.

[0071] There are usually many sensors on a terminal. For example, many sensors are configured on wearable electronic watches and bracelets to continuously monitor human behavior and health data for 24 hours.

[0072] For example, more than a dozen sensors can be configured on a smart watch. As long as the smart watch is in the powered-on state, there are sensors working. Among them, the sensors that are in the working state when the smart watch is in the screen-off state may include: an acceleration sensor, an optical heart rate sensor, a temperature sensor, etc. When the smart watch is in the screen-on state, in addition to the acceleration sensor, the optical heart rate sensor, the temperature sensor, etc., an ambient light sensor, an optical tracking sensor, etc. will also be turned on. Other sensors will work in different application scenarios. For example, when the compass APP is opened, the barometer sensor, the geomagnetic sensor, etc. will also enter the working mode.

[0073] In the embodiments of the present disclosure, an interruption refers to a situation that occurs during the running of a program, where the system presents a condition that must be immediately processed by the Central Processing Unit (CPU). For example, when a sensor generates data that requires waking up the processor for processing, at this time, the processor temporarily suspends the execution of the program and turns to process the program and execution process of this sensor data.

[0074] Step 202: Obtain the context of at least one sensor according to the interruption information.

[0075] Context is an ordered sequence of attributes that defines the environment for sensors residing within the environment. Context is created during the activation of the sensor, and the sensor is configured to request automatic services such as synchronization, real-time activation, security, etc. In computer technology, relative to a process, context is the environment in which the process executes. Specifically, it refers to various variables and data, including all register variables, files opened by the process, memory information, etc. The processor can be awakened by a GPIO interruption or a Timer interruption to obtain the context of the corresponding sensor.

[0076] Step 203: Read the sensor data of at least one sensor based on the context of at least one sensor.

[0077] Exemplarily, the sensor data is the corresponding data generated by the sensor according to its specific function over a period of time. For example, the data of an optical heart rate sensor can be 78 beats per minute, 85 beats per minute, 90 beats per minute, 88 beats per minute, 82 beats per minute, 84 beats per minute, 82 beats per minute, etc.; the data of a temperature sensor can be 36.4 °C, 36.5 °C, 36.3 °C, 36.7 °C, 36.9 °C, 36.8 °C, 36.5 °C, etc.

[0078] Step 205: Determine whether to wake up the processor according to the data volume in the first buffer, so as to extract the sensor data in the first buffer for processing.

[0079] The terminal realizes measurement, transmission, processing, and / or automatic control, etc. through internal sensors, and stores the obtained corresponding sensor data into the first buffer. The first buffer can be the buffer register (Buffer) in the free data block queue (SensorBufferFreeFIFO). Sensor data generated by one or more working sensors at different times will be stored in the first buffer, and the data volume in the first buffer will increase with the increase of the working duration.

[0080] Step 205: Determine whether to wake up the processor according to the data volume in the first buffer to extract the sensor data in the first buffer for processing.

[0081] In this embodiment, if it is monitored that the amount of data in the first cache reaches a preset threshold value, the terminal issues an instruction to wake up the processor, and extracts all the sensor data collected during this period from the first cache for processing.

[0082] Exemplarily, starting from when the terminal enters the working state, when it is monitored that the increased sensor data in the cache reaches the set data volume, the processor is woken up, and all the sensor data in the cache during this period is extracted for processing; then the data volume in the cache is continuously monitored until the increased sensor data in the cache reaches the set data volume again, and the processor is woken up again to process the newly added sensor data after the last time the processor was woken up; similarly, each time the processor is woken up, the sensor data within two adjacent time intervals is processed until the terminal enters the shutdown state. If it is monitored that the newly added data volume does not reach the set value, the processor is not woken up, which can reduce the number of times the processor is woken up to achieve the purpose of reducing power consumption.

[0083] Most sensors generate a small amount of data during the acquisition period, usually several bytes, resulting in a relatively small amount of data processed after the processor is woken up. The number of times the processor is woken up is related to the number of sensors and the acquisition frequency of the sensors. The more sensors there are and the higher the acquisition frequency, the more frequently the processor is woken up and the higher the power consumption.

[0084] Battery life is a very critical requirement for wearable electronic products. To reduce power consumption, based on the above content, the following describes Figure 3 a control system according to some embodiments of the present application.

[0085] This embodiment provides a control system, as Figure 3 shown, the sensor data acquisition scenario 300 includes an SSC microcontroller 301, a sensor 302, a cache register 303, and a processor 304. It mainly satisfies the following functions:

[0086] 1. Interrupt reception module design: Support different interrupt types and identify specific sensors through interrupts.

[0087] 2. Design dedicated instructions: Collect sensor data through a Serial Peripheral Interface (SPI) and an Inter-Integrated Circuit (I2C) interface.

[0088] 3. Design dual-logic channel concurrent execution instructions, which can concurrently read the data of 2 or more sensors.

[0089] 4. Cache management: Put sensor data into the cache according to the corresponding format, and different sensor data uses different buffer registers.

[0090] 5. Queue (FIFO) management: Put the collected sensor data into the FIFO and count the amount of data cached in the FIFO.

[0091] 6. Wake up the processor: After the FIFO reaches a certain threshold, wake up the processor to read the data from the cache and reduce the number of times the processor is woken up.

[0092] Most of the time, the electronic watch and bracelet are in the screen-off standby scenario. At this time, only the sensor is in the working state, and the processor needs to be continuously woken up to collect the sensor data for processing. Use the processor to complete the collection of sensor data.

[0093] In this embodiment, first, receive the interrupt information corresponding to at least one sensor; obtain the context of at least one sensor according to the interrupt information; then, based on the context of at least one sensor, read the sensor data of at least one sensor; store the sensor data in the first cache; and then determine whether to wake up the processor according to the amount of data in the first cache to extract the sensor data in the first cache for processing. In this embodiment, the SSC microprocessor can be used to replace the terminal processor to complete the sensor data collection. By uniformly managing all sensors, collect the data of all sensors and put them into the cache, and then wake up the processor when the amount of data in the cache reaches the set threshold. In this way, on the one hand, there is no need to use the processor to collect sensor data, and on the other hand, the number of times the processor is woken up is reduced, so as to achieve the purpose of reducing power consumption.

[0094] Based on the technical implementation content shown in the above embodiment, in order to further illustrate the specific implementation process of the method in this embodiment, this embodiment provides the following Figure 4 shown specific method, which includes:

[0095] Step 301, receive the interrupt information corresponding to at least one sensor.

[0096] Optionally, the interrupt information includes an interrupt type and an interrupt identifier;

[0097] In the embodiments of the present disclosure, the interrupt type mainly includes GPIO interrupt and / or Timer interrupt, etc., and the interrupt identifier can be used to determine the corresponding sensor.

[0098] Step 302, obtain the context of at least one sensor according to the interrupt information.

[0099] Based on the interrupt information in step 301 including an interrupt type and an interrupt identifier, correspondingly, step 302 may specifically include: determine the identifier of at least one sensor according to the interrupt type and the interrupt identifier; obtain the context of at least one sensor based on the identifier of at least one sensor.

[0100] Step 303: Read the sensor data of at least one sensor according to the context of the at least one sensor.

[0101] In some examples, the method of this embodiment further includes: determining the bus type used by each of the at least one sensor according to the interrupt type; generating a corresponding read instruction for each of the at least one sensor according to the context of the at least one sensor; and executing the read instruction by calling the bus interface corresponding to the bus type to read the sensor data of the at least one sensor.

[0102] Step 304: Store the read sensor data into the second cache corresponding to each sensor.

[0103] In some examples, the method of this embodiment further includes: if the sensor data read includes the sensor data of the target sensor and there is no second cache corresponding to the target sensor, applying for and allocating a second cache corresponding to the target sensor; and storing the sensor data of the target sensor into the second cache corresponding to the target sensor.

[0104] In the embodiments of the present disclosure, the number of second caches corresponds to the number of sensors. All working sensors first put the data into their respective second caches. Different sensors generate different amounts of data within the same period of time, and the amount of data in the second caches is also different.

[0105] Step 305: Determine to store the sensor data in the second cache into the first cache when the amount of data in the second cache is greater than or equal to the second preset threshold.

[0106] Exemplarily, if there is at least one target sensor among the working sensors that meets the condition for real-time data acquisition, determine the second preset threshold according to the second cache corresponding to each target sensor, where the second preset threshold is the amount of data cumulatively collected by the corresponding sensor system within a period of time.

[0107] In the embodiments of the present disclosure, setting the second preset threshold is to make the processing of sensor data more timely in devices or scenarios with high requirements for data real-time performance, which can improve the real-time performance of data reporting.

[0108] Step 306: Determine whether to wake up the processor according to the amount of data in the first cache to extract the sensor data in the first cache for processing.

[0109] In some examples, the method of this embodiment further includes: waking up the processor to extract the sensor data in the first cache for processing when the amount of data in the first cache is greater than or equal to the first preset threshold.

[0110] In the embodiments of the present disclosure, a preset threshold value can be used to determine whether to wake up the processor. Exemplarily, the target waterline value can be set to the amount of data generated by one or more working sensors within 1 s. Then, starting from the power-on time, when the working time of these sensors is 500 ms, the amount of data generated is less than the threshold value, and the processor will not be woken up; when the working time of the sensors is greater than or equal to 1 s, the amount of data generated is greater than or equal to the threshold value, then the processor is woken up and the sensor data generated during this period in the cache is extracted for processing.

[0111] Through the preset threshold value, the data collected by each working sensor according to different acquisition periods can wake up the processor to uniformly process the data in the cache when reaching the threshold value, reducing the frequency of the processor being woken up and at the same time reducing the power consumption during the process of the processor collecting sensor data.

[0112] As Figure 5 shown, the SSC microcontroller mainly includes the following parts:

[0113] 1. Interrupt control (INT Control) is used to receive sensor interrupts, including GPIO and Timer interrupts. 2. Interrupt handling (INT Handle) determines the sensor ID through the interrupt identity document (ID). 3. Context management (Context Manager) is used to manage sensor configuration information; apply for a buffer memory from the sensor data queue (SensorBufferPool) to save the read sensor data; execute the instructions corresponding to the sensor ID and generate instructions for I2C IF and / or SPI IF; determine whether the amount of sensor data collected reaches the threshold value and whether to put it into the idle data block queue. 4. M33 IF is used to configure the SPI bus; configure the I2C bus; configure the sensor context. 5. I2CIF is used to execute I2C instructions; select the corresponding I2C bus; collect sensor data through I2C and put it into the cache. 6. SPI IF is used to execute I2C instructions; select the corresponding I2C bus; collect sensor data through I2C and put it into the cache.

[0114] As an embodiment, based on the above content, the control method according to some embodiments of the present application will be described below in combination with Figure 6 description.

[0115] When powering on, the processor configures the I2C, SPI, sensor context, and idle data block queue managed by SSC through the M33 IF. The I2C configuration includes the number of I2C buses and the I2C bus register address space. The SPI configuration includes the number of SPI buses and the SPI bus register address space. The sensor context configuration includes the sensor ID, whether the bus type is SPI or I2C, the bus ID of I2C and / or SPI, and whether the interrupt type is Timer or GPIO. Information such as the address of the sensor read instruction, the threshold value for the sensor data volume to reach and be placed in the idle data block queue, and the ID of the sensor data queue for which cache is requested. The parameters of the idle data block queue include the FIFO depth and the threshold value for the cached data volume to wake up the processor. After the processor configures the SSC, it can enter the sleep low-power state.

[0116] After the configuration is completed, the interrupt control party waits for an interrupt from GPIO or Timer. After receiving the interrupt, it obtains the interrupt ID and interrupt type, and sends the interrupt-related information to the context management module.

[0117] The context management module calculates the sensor ID based on the interrupt ID and interrupt type. The sensor ID finds the corresponding sensor context, determines whether the bus type used by the sensor is SPI or I2C, generates instructions based on the instruction set base address in the sensor context, and sends the instructions to the cache instruction queue (CmdPendingFIFO) of the I2C IF and / or SPI IF in sequence.

[0118] The SPI IF or I2C IF reads the sensor data according to the instructions and sends the data to the context management module.

[0119] When the context management module receives the sensor data, if it finds that the sensor does not have a buffer register for storing data, it applies for a buffer register from the corresponding sensor data queue. The context management module puts the data into the buffer register in a certain format. If the data volume in the cache reaches the threshold value, the data in the cache is uniformly placed in the idle data block queue.

[0120] When the context management module finds that the cached data volume in the idle data block queue reaches the threshold value, it notifies the M33IF.

[0121] After receiving the notification, the M33 IF triggers an interrupt to wake up the processor. After the processor wakes up, it reads all the data cached in the idle data block queue.

[0122] Through the implementation mode of this embodiment, the SSC microprocessor can be used to replace the terminal processor to complete the acquisition of sensor data. By uniformly managing all sensors, collecting the data of all sensors and putting them into the cache, and then waking up the processor when the data volume in the cache reaches the set threshold value. In this way, on the one hand, there is no need for the processor to collect sensor data, and on the other hand, the number of times the processor is woken up is reduced, so as to achieve the purpose of reducing power consumption.

[0123] Further, as Figure 2 and Figure 4 a specific implementation of the method shown, this embodiment provides a control device, as Figure 7 shown, the device includes: an acquisition unit 41, a storage unit 42, and a determination unit 43.

[0124] The acquisition unit 41 is configured to receive interruption information corresponding to at least one sensor; obtain the context of the at least one sensor according to the interruption information; and read the sensor data of the at least one sensor according to the context of the at least one sensor.

[0125] The storage unit 42 is configured to store the sensor data in a first cache.

[0126] The determination unit 43 is configured to determine whether to wake up the processor according to the data volume in the first cache, so as to extract the sensor data in the first cache for processing.
