Abstract

The invention provides a multi-operating-system same-screen display method. The method comprises the steps that a display controller obtains to-be-displayed content of all layers from a plurality of operating systems and layout configuration information corresponding to all the layers; based on the layout configuration information corresponding to the layers, the display controller adjusts to-be-displayed contents corresponding to the layers and integrates the to-be-displayed contents of the layers for display; wherein the display controller comprises a plurality of layer processing units, the plurality of layer processing units are configured into a plurality of groups, and the layer processing units in the same group are used for adjusting to-be-displayed contents of different layers from the same operating system. The invention further provides a multi-operation system same-screen display device, the display contents of the multiple operation systems are displayed on the same display screen, and the utilization rate of hardware resources is increased.

Description

technical field [0001] The embodiments of the present application relate to the technical field of image display, and in particular, to a method and device for displaying multiple operating systems on the same screen. Background technique [0002] Multiple operating systems can run in the system-on-chip. In the prior art, in order to meet the display requirements of each operating system, a set of dedicated display controllers and display interfaces for each operating system is usually set on the system-on-chip, and then an external independent display controller is provided. display. [0003] In the above-mentioned multi-operating system display method, since the number of display controllers, display interfaces and display screens will increase with the increase of operating systems, the hardware resources of the system-on-chip are required to be relatively large, the development cost is relatively high, and the This reduces the difficulty of deploying the display and its...
