Abstract
A graphic accelerator includes a RGB/YUV conversion unit converting color information of the RGB format included in the drawing instruction into a format including luminance and color difference components, a drawing instruction execution unit compressing the color difference component converted by the RGB/YUV conversion unit and generates pixel information according to the drawing instruction, a screen data output unit expanding pixel information generated by the drawing instruction execution unit, and a YUV/RGB conversion unit converting the pixel information expanded by the screen data output unit into pixel information of the RGB format. Therefore, the amount of data of the color difference component can be reduced to improve the processing speed.
