The M7 coprocessor obtains motion data, and the m7 processor obtains motion data.

The M7 coprocessor obtains motion data, and the m7 processor obtains motion data.
NSObject
NSObject is the root class of most objective-c class hierarchies.
　　
CMAltimeter
Use the CMAltimeter object to start delivery of the altitude-related data application.
　　
CMAttitude
An instance of the CMAttitude class represents the attitude of the measuring device at a time point.

CMPedometer
Use the CMPedometer object to obtain pedestrian-related data.
　　
CMPedometerData
The CMPedometerData object encapsulates information about the user's walking distance.
　　
CMStepCounter
The CMStepCounter class provides the number and devices that the user has taken.

The CMStepCounter class provides the number and devices that the user has taken. Information collection and appropriate built-in hardware and storage devices, so that you can run queries to determine your most recent physical activity. You can use this class to collect the data of the current step and historical data. (Changes will be made after 8.0. Be aware of the changes during upgrade)

Use the CMPedometer object to obtain pedestrian-related data. You use a pedometer to increase or decrease the distance between the number of retrieval steps and other information and the number of floors. The history data of the pedometer Object Management cache can be queried or data processing that requires real-time updates. Use a pedometer object to create an instance of this class and call appropriate methods. Use the queryPedometerDataFromDate: so far: withHandler: Method to retrieve data that has been aggregated. Real-time update: Use startPedometerUpdatesFromDate: withHandler: To start delivery provided by the event handler. (Supported starting from 8.0)

The CMPedometerData object encapsulates information about the user's walking distance. You do not create instances of this class yourself. Instead, you use the CMPedometer object to request the data system of the pedometer. Package the data for each request into an instance of this class and deliver it to the registered processor pedometer object. (Supported starting from 8.0)

/* *  CMStepCounter * *  Discussion: *      CMStepCounter allows access to the approximate number of steps a user has taken *      with a device.

What does the M7 coprocessor of iPhone 5S work?

Whether you are walking, running, or even driving, M7 coprocessor is available. Since M7 coprocessor knows when you are in a car, the iPhone 5S won't ask if you want to join the wireless network that passes. If your mobile phone remains inactive for a long time, for example, when you are sleeping, the M7 coprocessor reduces network detection and Saves battery power. In the chip field, how to extend the cell phone's endurance is always a very difficult problem. The increased battery capacity will always fight against the gradually expanding screen size, which can be said to be no solution. What chip manufacturers can do is to enhance internal control. The product director of Qualcomm, the boss of the chip industry, said: The Power Consumption Optimization of mobile phones is endless. Sometimes you cannot determine whether to reduce the power consumption because you do not know what the mobile phone is doing, however, after a sensor is added, the mobile phone will become more intelligent, start to understand the user's behavior, and make more detailed adjustments. The M7 coprocessor in the latest iPhone5S is such a sensor data processing center. In Apple's official description, M7 is used to "continuously measure motion data", including data from the accelerator, gyroscope, and compass. I expect that data from light sensors, distance sensors, and gravity sensors will be processed by M7 coprocessor in the future. In addition to coprocessor M7, iPhone 5S also provides an API called "CoreMotion" for a third party to call M7 coprocessor. The Demo example of the press conference is that Nike's new motion App "Nike + Move" calls the M7 coprocessor and GPS chip to track users' daily behaviors. The Nike App calls GPS for M7 processing (using APIs to access coprocessor), which can save user power.

Is the M7 coprocessor the start of an Apple map attack?

Although many people think that Apple's new product release was poor in the past few days, in addition to the spoof, we should also see something that can be called a bright spot. M7 coprocessor is one of them. The concept of co-processor was not the first to emerge. The X8 Computing System in Moto X, which was recently released, is somewhat similar in terms of energy conservation and continuous awareness. Samsung Galaxy S4, Note 2, and meizu MX 3 have similar Sensor Hub technologies.
Let's repeat the functions of M7:
Whether you are walking, running, or even driving, M7 coprocessor is available. Because the M7 coprocessor knows when you are in a driving vehicle, the iPhone 5S does not ask if you want to join the passing wireless network. If your mobile phone remains inactive for a long time, for example, when you are sleeping, the M7 coprocessor reduces network detection and Saves battery power.
The strength of Google Maps has kept Apple Maps unstarting, even if Apple put it in a prominent position in App Store. According to the 9to5Mac report, after the apple map is updated, the map application can use the M7 coprocessor to help users find their own car. The M7 coprocessor can sense that users can stop driving and have their mobile phones record locations of vehicles. When users need to use vehicles again, with the help of M7 and Apple map, you can easily find your own car.
This is only an application scenario. It is said that Apple is still developing other map features, such as indoor maps and public transportation. Direct evidence is that Apple recently acquired two related companies, WifiSLAM and mongostop, and previously acquired several companies focusing on transportation. You cannot insert new data into the new Apple map.
In addition, Apple also has other new features that can be used on Apple Maps, such as iBeacons, which uses low-power bluetooth technology at the press conference. Although the specific technical details are unclear, iBeacons can provide indoor map and other micro-location services based on the currently known information, provides preferential information, hard decoding, and positioning services for any device in a specific region.
