GRAPHIC ACCELLERATOR REDUCING AND PROCESSING GRAPHICS DATA

摘要

A graphic accelerator includes a RGB/YUV conversion unit converting color information of the RGB format included in a drawing instruction into a format which includes luminance and color difference components, a drawing instruction execution unit for compressing the color difference component converted by the RGB/YUV conversion unit to generate 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 conversio n unit which converts the pixel information expanded by the screen data output unit into pixel information of the RGB format. Therefore, the data amounts of the color difference componen t can be reduced to improve the processing speed.
