Abstract:
1. A three-dimensional graphic drawing apparatus comprising: a geometry processing unit for receiving three-dimensional data, and for performing a geometry process on the three-dimensional data so as to generate vertex data; a rendering processing unit for performing a rendering process on the vertex data generated by said geometry processing unit so as to generate pixel data; and a clock control unit for controlling operations of said geometry processing unit and said rendering processing unit by using clock signals respectively supplied to said geometry processing unit and said rendering processing unit, wherein the geometry processing unit outputs a busy signal while performing the geometry process, the rendering processing unit outputs a busy signal while performing the rendering process, and the clock control unit supplies the clock signals to said geometry processing unit and said rendering processing unit by using the busy signal output by said geometry processing unit and the busy signal output by said rendering processing unit so that said geometry processing unit and said rendering processing unit operate alternately.
