<p>A reference address generation unit (72) receives a UV coordinate value from a Shader (30), converts it into a reference address for referencing a texture, and references a texture map or a command map stored in a texture memory (76) according to the reference address. The value referenced from the texture map is supplied to an interpolation unit (74) and the value referenced from the command map is written into a command buffer (52). The interpolation unit (74) performs texture mapping to generate a color value corresponding to the UV coordinate value of the pixel and supplies the color value via a data path to the Shader (30). A command decoder (62) reads out a command code held in the command buffer (52), decodes the command code, and supplies a control signal for executing the decoded command, to the Shader (30).</p> |
