Abstract

The embodiment of the invention provides a control method of a single-chip heterogeneous system and wearable equipment, and belongs to the technical field of embedded systems. The method comprises thesteps of loading target application software; if the software logic corresponding to the current target application software belongs to the first type of software service, awakening a first subsystem, acquiring the control right of the shared peripheral by the first subsystem, and processing the first type of software service by using the shared peripheral; after the first subsystem processes thefirst type of software service, if the second type of software service needs to be executed, enabling the second subsystem to obtain the control right of the shared peripheral, use the shared peripheral, use the migrated software logic to continue to process the second type of software service, and enabling the first subsystem to give up the control right of the shared peripheral and enter a low-power-consumption mode; and if the software logic corresponding to the current target application software belongs to the second type of software service, enabling the second subsystem to process thesecond type of software service by using the shared peripheral. High-performance processing capacity is reserved, cost is reduced, and power consumption is saved.

Description

Technical field [0001] The present disclosure relates to the technical field of embedded systems, in particular to a control method of a single-chip heterogeneous system and a wearable device. Background technique [0002] In the prior art, electronic devices such as high-performance watches generally adopt a multi-core design. When in a high-performance working state, multiple processor cores enter the running state, thereby increasing sufficient computing power to support complex software applications. When the user exits a complex software application, some cores are closed, leaving only a few cores to continue running simple software applications, such as refreshing time, playing music, etc. Using this technology can save the power consumption of the smart watch and extend the standby time. However, in order to support complex applications, a multi-core processor generally prefers high performance and high power consumption in its production process. Even if a single core is...
