Abstract: A graphics primitive sharing method is provided and is related to the terminal field. When drawing interface content, a secondary chip in an electronic device obtains a set of controls corresponding to interface content. The secondary chip delegates a control whose drawing effect is poor in the set of controls to a primary chip to perform drawing. The secondary chip composites a graphics primitive drawing result of the secondary chip and a graphics primitive drawing result of the primary chip, and sends a composited result to a display.

Abstract: The present disclosure relates to service data transmission methods and devices. One example method includes establishing a first Bluetooth logical channel with a first main control chip of a wearable device and a second Bluetooth logical channel with a second main control chip of the wearable device, where the first main control chip and the second main control chip have different processing capabilities and energy consumption, and sending, based on an interaction channel corresponding to a service, service data to the first main control chip through the first Bluetooth logical channel or to the second main control chip through the second Bluetooth logical channel.
