3-dimensional graphic plotting apparatus
First Claim
1. A three-dimensional graphic drawing apparatus including 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, and 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, said apparatus comprising:
- 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.

Abstract
A clock control unit (7) detects completion of data processing based on a busy signal BSY1 output by a geometry processing unit (4) and a busy signal BSY2 output by a rendering processing unit (5). The clock control unit (7) controls supply of a clock signal CLK1 to the geometry processing unit (4) and supply of a clock signal CLK2 to the rendering processing unit (5) so as to cause the geometry processing unit (4) and the rendering processing unit (5) to alternately operate.
