technical field

The present application relates to the field of communication technology, and in particular to a chip system and a control method.

Background technique

As a wearable mobile device, a smart watch not only has the function of indicating time, but also has various data processing functions such as calling, navigation, monitoring, payment and interaction. Due to the limited design space of the smart watch, the battery capacity of the smart watch is inevitably limited. Therefore, how to maximize the battery life of the smart watch under the limited battery capacity has become an urgent problem to be solved.

The prior art provides a control device including a main control subsystem and a secondary control subsystem. The control device controls the smart watch by switching different subsystems in different states, so as to reduce power consumption in the smart watch. FIG. 1 is a schematic structural diagram of a control device of a smart watch, which has a working state and a dormant state (that is, a screen-off state). As shown in Figure 1, the control device includes: a main control subsystem, a secondary control subsystem, a display subsystem and a switching module. The display subsystem is connected with the switch module, the switch module is connected with the main control subsystem and the auxiliary control subsystem respectively, and the main control subsystem is connected with the auxiliary control subsystem. Specifically, when the main control subsystem detects that the smart watch has entered a dormant state, it sends the first state synchronization information to the sub-control subsystem, and after the sub-control subsystem receives the first state synchronization information, Obtain the control right of the display subsystem to control the display subsystem, the first state synchronization information is used to indicate that the smart watch is in a dormant state; when the smart watch is in a dormant state, the sub-control subsystem receives a wake-up signal Afterwards, send the second state synchronization information to the main control subsystem, the second state synchronization information is used to wake up the main control subsystem, when the main control subsystem is woken up, the display subsystem is obtained through the switching module Control rights to control the display subsystem.

Wherein, when the smart watch is in a dormant state, the main control subsystem is in a dormant state, and usually the power consumption of the main control subsystem is higher than that of the sub-control subsystem, so when the smart watch is in a dormant state, the sub-control subsystem The system controls the display subsystem, which can reduce the power consumption of the smart watch, thereby improving the battery life of the smart watch. However, the sub-control subsystem only controls the display subsystem when the smart watch is in a dormant state. When the smart watch is in a low-power working state, it still controls the display subsystem through the high-power main control subsystem, resulting in power consumption The decrease is not obvious.
