Abstract
A shader sends a 'completely full' signal to a buffer control unit when a head pixel in a first pass input from a DDA arrives at a final stage of a pipeline process. When the head pixel in the first pass arrives at a stage in the middle of the pipeline process, the shader sends an 'almost full' signal to the buffer control unit and a primitive generating unit. Upon receiving the “almost full” signal, the primitive generating unit suspends the generation of rendering primitives in the first pass and starts generating rendering primitives in the second pass. Upon receiving the “almost full” signal, the buffer control unit supplies the rendering primitives in the first pass from the setup processing unit to the DDA via a temporary buffer. Upon receiving the “completely full” signal, the buffer control unit switches to a second pass and directly supplies the rendering primitives in the second pass from the setup processing unit to the DDA.
