PURPOSE:To use a general process address for graphic display as it is and to attain the reference to a graphic address space by securing the coincidence between a graphic address and the general process address. CONSTITUTION:A shared area 39 in a process address space which receives the frequent reference from a graphic display control means is mapped to the last area of a graphic address space 31. Then another process address space 33 is mapped continuously to the space 31 excluding the area 39 so that the coincidence is secured between a process address and a graphic address. Thus the process address can be directly used as a graphic address of a graphic display system. |
