GRAPHICS PROCESSING SYSTEM FOR DETERMINING WHETHER TO STORE VARYING VARIABLES INTO VARYING BUFFER BASED AT LEAST PARTLY ON PRIMITIVE SIZE AND RELATED GRAPHICS PROCESSING METHOD THEREOF

摘要

A graphics processing system includes a decision logic and a varying buffer control circuit. The decision logic sets a control signal by checking at least one criterion, wherein the at least one criterion includes a first criterion, and a checking result of the first criterion depends on a size of a primitive. The varying buffer control circuit refers to the control signal to determine whether to store varying variables of the primitive into a varying buffer.
