A method and system for operating in a single display mode operation and a dual pipe mode of operation is disclosed. The method and system includes operating in a dual pipe mode of operation in which each display pipe transmits data from a respective buffer to an associated display. The method and system further includes operating in a single display mode of operation in which one display pipe transmits data from a plurality of buffers to an associated display.

Technique for extended idle duration for display to improve power consumption

A disclosed technique includes transmitting data in a first buffer associated with a first display pipe to a first display associated with the first display pipe; transmitting data in a second buffer associated with a second display pipe to the first display; requesting wake-up of a memory; and refilling one or both of the first buffer and the second buffer from the memory.

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.

Single display pipe multi-view frame composer method and apparatus

A video device having data lanes and a method of operating the video device includes obtaining a stream of debug data in response to a test operation, framing the stream of debug data independent of establishing a video blanking period, and transmitting the framed stream of debug data across one or more data lanes of the video link for operation between a video source device and a video sink device. The method also includes generating a stream of video data related to the test operation, framing the stream of video data to establish a video blanking period, and transmitting the framed stream of debug data concurrently with the framed stream of video data across the one or more data lanes of the video link.
