(57) Abstract It is connected by the graphic bus and with the graphic processor (115) is the graphic subsystem which includes RAMDAC (120) which is mounted on the separate integrated circuit tip/chip. With a certain execution example, it processes graphically and, responding to graphic command, digital image information rendering in order to remember digital image information in memory, it is constituted. RAMDAC IC includes conversion unit (133), conversion unit includes color mapping unit (132), and the digital - analog transmitter (134) converts expression of digital image information to the analog signal of one and or more in order to drive video indication, is constituted. Graphic subsystem furthermore includes the direct memory access (DMA) controller (123) which is mounted on the 2nd integrated circuit tip/chip. The DMA controller forms the read-out demand in order to remove the digital image information which is remembered in memory in order to be able to give to conversion unit digital image information, is constituted. The DMA controller is formed, forming entry cycle, the digital RGB indicatory data which it receives from color mapping unit in conversion unit, being given, in order to be remembered in the territory of specification of memory, furthermore. With another execution example, as for graphic subsystem, it is possible to include the digital video interface (185) which is mounted on the 2nd integrated circuit tip/chip. Digital video interface is formed, in order to give the digital video output which the digital RGB indicatory data receiving and is encoded to the digital video output port from color mapping unit. Digital video interface is formed the digital video which is encoded receiving and giving the digital display data which is decoded from the digital video input port, in order to remember in the device of digital VCR and the like, furthermore.
