PURPOSE:To prevent decrease of performance of a system and data processing efficiency, by splitting the system bus into graphic information buses and code information buses, in a computer system handling graphic information and code information. CONSTITUTION:When graphic information is transmitted to a system unit 100 from an in-line data station 200, a data station 202 transmits transaction information to a local line conrol processor 105 via a code information in-line bus 401. The graphic information is in multiplex control and transmitted to a local line control processor 106 via a graphic information in-line bus 400. Thereafter, a system control processor 103 processes the graphic information stored in a temporary buffer memory 111 temporarily based on the address information and the transaction information. |
