PROBLEM TO BE SOLVED: To eliminate the necessity of a high-performance graphics subsystem by branching graphics inplementation between a host computer and a graphics subsystem. SOLUTION: The graphics subsystem of a digital computer system 10 is composed of a graphics adapter 20. A host system 10A is provided with a memory controller 30 mutually connected with a main processor 11 and a main memory 12. This controller is provided for controlling the processing and storage of graphics information related to picture elements, which exist in the main memory 12, to be displayed. Namely, the memory controller 30 generates masked direct frame buffer access data structure, the host system 10A and the graphics subsystem are mutually connected through a bus 16, and this data structure is trarnsmitted from the host system 10A to the graphics subsystem. |
