Embodiment 1

[0044] figure 1 It is a schematic structural diagram for showing a system-on-a-chip. The working mode management method of the SoC provided by this embodiment can be applied to figure 1 SoC shown. Such as figure 1 As shown, the system-on-a-chip includes a main control subsystem, a secondary control subsystem and multiple functional subsystems. Wherein, the main control subsystem and the auxiliary control subsystem are respectively connected to the functional subsystem through an interruption line, and the main control subsystem and the auxiliary control subsystem are connected through an interruption line.

[0045] This embodiment provides a working mode management method of a SoC, such as figure 2 shown.

[0046] In work mode, perform the following steps:

[0047] Step S100, the main control subsystem controls the functional subsystem to execute corresponding functions, and responds to interrupt signals from the functional subsystem and the secondary control subsystem....

Embodiment 2

[0075] This embodiment provides a system-on-a-chip, including a main control subsystem, a secondary control subsystem, and multiple functional subsystems.

[0076] In the working mode, the main control subsystem is configured to control the functional subsystem to perform corresponding functions, and respond to interrupt signals of the functional subsystem and the secondary control subsystem.

[0077] In the sleep mode, the sub-control subsystem is configured to respond to the interrupt signal of the functional subsystem, and the main control subsystem is configured to prohibit responding to the interrupt signal of the functional subsystem.

[0078] In the ultra-low power consumption mode, the main control subsystem is configured to be powered off, and the secondary control subsystem is configured to respond to an interrupt signal of the functional subsystem.

[0079] In the working mode, the main control subsystem is configured to switch to the sleep mode if no data sent by a...

Embodiment 3

[0095] This embodiment provides a smart wearable device, including the system-on-a-chip as described in Embodiment 2.

[0096] In some optional implementation manners, the smart wearable device above further includes a touch screen and multiple sensors, wherein the touch screen and the sensors are respectively electrically connected to the system-on-a-chip. In this embodiment, the user can operate the content displayed on the smart wearable device through the touch screen, and the smart wearable device makes different responses based on different operations of the user.

[0097] In some optional implementation manners, the aforementioned sensors include a heart rate sensor, an acceleration sensor, a gyroscope sensor, and the like. Among them, the sub-control subsystem in the SoC is used to realize the functions of the Sensor Hub, including real-time control of sensors, fusion of data from different types of sensors, and functions that can only be realized by combining multiple...

Abstract

The invention discloses a system-on-chip and a working mode management method thereof and intelligent wearable equipment. The working mode management method of the system-on-chip comprises the following steps that in a working mode, the main control subsystem controls the function subsystem to execute corresponding functions and responds to interrupt signals of the function subsystem and the auxiliary control subsystem; in the sleep mode, the auxiliary control subsystem responds to the interrupt signal of the function subsystem, and the main control subsystem forbids responding to the interrupt signal of the function subsystem; and in the ultra-low power consumption mode, the main control subsystem is powered down, and the auxiliary control subsystem responds to an interrupt signal of thefunctional subsystem. The main control subsystem and the auxiliary control subsystem alternately respond to interrupt signals of the function subsystem, a working mode, a sleep mode and an ultra-low power consumption mode are provided for the system-on-chip, and power consumption of the system-on-chip is saved to the maximum extent on the premise that normal function requirements of the system-on-chip are met.

Description

technical field [0001] The present invention relates to the field of chip technology, in particular to a system-on-chip (System on Chip, SoC) and its working mode management method, and an intelligent wearable device. Background technique [0002] Smart wearable device is a general term for the application of wearable technology to intelligently design daily wear and develop wearable devices, such as watches, bracelets, glasses, clothing, etc. Among them, smart watches are the most widely used type of smart wearable devices. [0003] In the product realization of smart watches, there are currently the following two methods to save power consumption: First, use AOD (Always ON Display) technology to display some areas of the screen after the smart watch is turned off to achieve low power consumption. The purpose of power saving; second, the temporarily unused subsystem enters the sleep mode and only consumes standby current. Due to the limitation of physical size, smart watc...
