When performing 'time warp slice' rendering for a virtual reality display, the application rendering () of the images required for the application that requires the virtual reality display is synchronised () to the display frame rate and treated as a 'normal' priority task () in terms of its scheduling on a host processor. The time warp slice rendering () to render the time warp &#x201c;slices&#x201d; into the display buffer () of the display () for scanning out () as the display panel is being refreshed is effected as a &#x201c;real time&#x201d; priority task (). To do this, the rendering task setup processing that must be performed on the host processor for that rendering task is scheduled using an earliest deadline first scheduling policy and is synchronised () to specific, recurring display events () that allow the &#x201c;real time&#x201d; priority time warp slice rendering task setup processing on the host processor to be triggered at specific points in the scan out period () of the display ().
