Abstract: An electronic apparatus and method of operating the electronic apparatus, to simultaneously display execution screen images of a first OS and a second OS are provided. The method includes obtaining screen image data of the second OS based on graphic data processed by the second OS; obtaining, by the first OS, at least one of control information related to the screen image data of the second OS and memory mapping information of the second OS; converting the screen image data of the second OS into graphic data of the first OS based on the at least one of the control information and the memory mapping information; generating screen image data of the first OS based on the graphic data of the first OS, the screen image data of the first OS including the screen image data of the second OS; and displaying the screen image data of the first OS.

Abstract: A method of composing and displaying screen images includes transmitting a screen image of a guest operating system (OS) to a host OS, in response to the guest OS and the host OS exclusively or jointly accessing a graphics processing unit (GPU) in a pass-through or mediated pass-through environment via GPU virtualization; generating a composition screen image by transforming the screen image of the guest OS into a texture and composing the texture with a texture screen image of the host OS; and displaying the composition screen image.
