Abstract

Embodiments of the present disclosure provide a control method of a single-chip heterogeneous system and a wearable device, which belong to the technical field of embedded systems. The method includes: loading the target application software; if the software logic corresponding to the current target application software belongs to the first type of software service, waking up the first subsystem, the first subsystem obtains the control right of the shared peripheral, and uses the shared peripheral to process the first type Software business; after the first subsystem has processed the first type of software business, if it needs to execute the second type of software business, the second subsystem obtains the control right of the shared peripheral, uses the shared peripheral, and uses the migrated software logic to continue Process the second type of software business, and the first subsystem gives up the control of the shared peripherals and enters the low power consumption mode; if the software logic corresponding to the current target application software belongs to the second type of software business, the second subsystem uses the shared peripherals for processing The second type of software business. Retain high-performance processing capabilities, reduce costs, and save power consumption.

Description

technical field [0001] The present disclosure relates to the technical field of embedded systems, and 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 complex software applications, some cores are turned off, leaving only a few cores to continue running simple software applications, such as refreshing time and playing music. Using this technology, the power consumption of the smart watch can be saved and the standby time can be extended. However, in order to support complex applications, the production process of multi-core processors is generally biased towards high performance and high power cons...
