Abstract:
A method to control a graphics rendering pipeline having multiple stages that process a sequence of frames of graphics data output from an application for display, comprising the steps of:(a) inserting stall tokens in between frames of the graphics data; (b) stalling processing of the graphics data in the graphics rendering pipeline, such that the graphics rendering pipeline is stalled in response to a stage of the graphics rendering pipeline encountering an inserted stall token; (c) generating a display interval complete signal when a frame of graphics data stored in one buffer of a display stage of the graphics rendering pipeline has been processed for display; (d) unstalling processing of the graphics data in the graphics rendering pipeline when the display interval complete signal has been generated; and (e) storing stall data representative of frame complete markers and stall tokens, wherein the stall data comprises at least one data sequence associating frame complete markers with stall tokens.
