PURPOSE: A CRT controller is provided to increase a display processing speed by increasing a pliability of an RGB data structure and reducing a burden of a software. CONSTITUTION: A frame buffer(100) stores an RGB data according to an address signal. A FIFO memory(110) sequentially receives and outputs the RGB data from the frame buffer(100). A FIFO controller(120) controls an operation of the FIFO memory(110). A synchronous signal generator(150) generates a synchronous signal. An RGB divider(130) divides the RGB data from the FIFO memory(110) into R, G, and B signals. An RGB converter(140) converts the R, G, and B signals form the RGB divider(130) into predetermined RGB formats. An RGB processor(160) displays the RGB data from the RGB converter(140) in synchronism with the synchronous signal from the synchronous signal generator(150).
