Abstract
A method and apparatus for providing multi-view composed frames uses a single display pipe mechanism. The single display pipe includes, in one example, a memory requestor that fetches multi-view data from a frame buffer using a plurality of viewports. The single display pipe may also include a multi-view packer. Each viewport of the single display pipe has access to a frame buffer holding multi-view frame data, and may be configured to have access to different areas of the frame buffer. In this fashion the single display pipe may fetch data representing more than one view of a multi-view frame. Additionally, the multi-view packer combines the data fetched from one or more of the viewports to form a multi-view frame to be supplied for display.
