Two Apple patents have appeared at the US Patent & Trademark Office that involve graphics and displays.
Patent number 20100164964 is for a display system with improved graphics abilities while switching graphics processing units. That's something high-end MacBook Pros can do now, but Apple may plan to carry it further.
The patent involves methods and apparatuses for improving graphics abilities while switching between graphics processing units (GPUs). Some embodiments may include a display system, including a plurality of graphics processing units (GPUs) and a memory buffer coupled to the GPUs via a timing controller, where the memory buffer stores data associated with a first video frame from a first GPU within the plurality of GPUs and where the timing controller is switching between the first GPU and a second GPU within the plurality. The inventors are Kapil V. Sakariya, Victor H. Yin and Michael F. Culbert.
