CONTROLLER FOR MULTI-WINDOW CONTROL INFORMATION

摘要

PURPOSE:To transfer the window control information at a higher speed than other information by checking an information controller corresponding to a designated window in the high priority areas at firs and then the low priority areas in case no contents are obtained from the high priority areas. CONSTITUTION:A priority deciding device 25 checks the priority of the window control information stored in an information control register 22 and shows this check result. A window control information controller 26 produces, deletes and transfers the window control information through the control of the register 22 and the device 25. Furthermore a data transfer device 24 is added together with an arithmetic register 23. The controller 26 transfers the window control information to an area designated when the window control information corresponding to the designated window is detected. Thus the designated window control information can be sent to the corresponding window at a higher speed than other information. Then the reconstitution is accelerated for the multi- window display with replacement and deletion of windows.
