• WhitePaper - Graphics Sharing and Distributed HMI v3

Technology Briefs

 Sharing a physical display across multiple operating systems

• This brief describes the Display Sharing category which provides support in hardware for compositing the display output from multiple operating systems into a single final display buffer. Using this, a combined HMI can be created from independently operating systems without any additional interaction
