<p>PURPOSE:To efficiently and separately use plural displays having respectively different contexts by dividing the module constitution of software into a virtual graphics output space managing part in a virtual storage space and a control part for controlling individual display mapped on the space. CONSTITUTION:A data storing VRAM 11, a program storing ROM 12 and a CRT 13 are connected to a CPU 10. The CPU 10 inputs information from an application program and instruction information or the like from a keyboard 14 and a virtual storage space 20 is prepared. Areas in the space 20 can be used by the CRT and used also by CRT1 to CRT3 of display devices 41 to 43 through a module 40. For instance, areas 21 to 23 in the space 20 are installed, assigned and supplied to the devices 41 to 43 by a vector information meta picture protocol through the module 40.</p> |
