Abstract
A graphics pipeline with components that process frames by portions (e.g., pixels or rows) or slices to reduce end-to-end latency. Components of a pipeline process portions of a same frame at the same time. For example, as graphics data for a frame is being generated and fills a framebuffer, once a certain portion of video data less than the whole frame (slice or sub-frame) becomes available, before the corresponding frame is finished filling the framebuffer, the next pipeline component after the framebuffer, for instance a video processor for color conversion or an encoder, begins to process the portion of the frame. While one portion of a frame is accumulating in the frame buffer, another portion of the same frame is being encoded by an encoder, and another portion of the frame might be being packaged by a multiplexer, and a network socket might start streaming the multiplexed portion.
