Background
Most portable smart devices have built-in sensors for measuring motion, screen orientation, various environmental conditions, etc. These sensors can provide highly accurate raw data, and are well suited for use in monitoring three-dimensional movement or positioning of a device, or monitoring changes in the environment surrounding the device.

Also, weather applications may use temperature and humidity sensors of the device to calculate and report dew points, while travel applications may use geomagnetic field sensors and accelerometers to report compass orientations. The portable smart device monitors and knows the surrounding environment through constantly active sensors. With the ever increasing functional demands of end products, devices integrate more and more sensors, thereby generating a large amount of periodic data, so that it becomes necessary to integrate a more powerful CPU (central processing unit) in order to perform more and more calculations; this necessitates an enlarged chip design size, increasing cost and power consumption.

Example 1
As shown in fig. 1, the sensing data processing device of the intelligent terminal of the present embodiment includes a SoC platform 1, an application processor 2, and a plurality of sensing elements 3, and a sensing data controller 4 is integrated in the application processor 2. The SoC platform 1 is a multi-core SoC platform 1.
The application processor 2 is mounted on the SoC platform 1.
Each sensor element 3 is in communication with a sensor data controller 4;
the sensor data controller 4 is connected to the sensor element 3 by I2C, SPI, or the like. The sensor data controller 4 operates at the system clock speed of the intelligent terminal.
The sensing element 3 includes, but is not limited to, an acceleration sensor, a gyro sensor, a magnetic sensor, a light sensor, and a distance sensor, so as to collect different types of sensing data to meet different actual requirements.
The sensing data controller 4 is used for acquiring sensing data acquired by the sensing element 3 and processing and/or storing the sensing data. The sensor data controller needs to periodically collect sensor data, such as sensor polling and reading operations. The specific processing mode of the sensing data of different types can be preset, and the processing mode of the sensing data can be reset or adjusted according to actual requirements, so that different actual requirements can be met.
When the sensor data controller 4 processes the working state, other devices except the sensor data controller 4 in the application processor 2 are all in a dormant state, so that most of devices in the application processor AP are kept in the dormant state under the condition of reducing one CPU core, and the power consumption of a processing system is effectively reduced.
In addition, the sensing data controller 4 is further configured to generate a first control instruction to control the working state of the corresponding sensing element 3;
the working state comprises power consumption parameters, power-on or power-off and the like. For example, when some of the sensing elements are in a state of being powered on but not needing to collect data most of the time, the sensing elements can be directly controlled to be powered off through the first control instruction, so that power consumption is saved to the greatest extent; or adjust its power consumption parameters to reduce overall power consumption.
The sensing data controller 4 is in communication connection with a memory in the intelligent terminal;
the sensing data controller 4 is used for transmitting the sensing data to the memory for storage; or, the sensing data controller 4 is used for reading stored sensing data from the memory.
The sensing data controller is directly connected with the memory, so that data can be directly transmitted between the sensing data controller and the memory, the problem that the existing data transmission process involves multiple read-write operations is solved, the data transmission process is simplified, and the data transmission efficiency is improved.
The sensing data controller 4 is electrically connected with a power-on pin of the application processor 2;
other devices in the AP (main processing, etc.) need only wake up upon special event operations, such as:
the sensing data controller 4 is configured to determine whether the data amount of the stored sensing data meets a first set threshold, and if yes, generate a first trigger signal and input the first trigger signal to an upper power pin to control other devices in the application processor 2 to enter a working state; namely, after the sensing data to be processed by the AP reaches a certain quantity, the AP is awakened to start centralized processing on the data, so that the power consumption is reasonably and effectively saved while the data processing flow is ensured.
In addition, the sensing data controller 4 is configured to determine whether the sleep time of other devices in the application processor 2 meets a second set threshold, and if so, generate a second trigger signal and input the second trigger signal to the power-on pin to control the other devices in the application processor 2 to enter a working state. I.e. the AP is awakened to start working at fixed time through the sensing data controller.
Of course, other trigger conditions may be reset according to the actual requirement to wake up the AP to start working.
The sensing data controller 4 is in communication connection with a target element in the intelligent terminal;
the sensor data controller 4 is configured to generate a second control command to control the operating state of the target element. The other devices may be one or more specific elements in the intelligent device, and may specifically determine and adjust according to the actual situation.
The sensing data controller can control other devices, so that the sensing data controller is effectively utilized, and the resource utilization rate is improved.
The sensing data controller 4 is electrically connected with a PMU (power management unit) of the intelligent terminal;
the sensing data controller 4 is used for generating a third control instruction to control the power management unit to turn off or turn on the intelligent terminal. The whole intelligent terminal is opened or closed through the sensing data controller, so that more operation requirements are met.
