DISTRIBUTED WINDOW CONTROLLER

摘要

PURPOSE:To execute a program in a data processor while exchanging data between plural I/O controllers by providing the title device with plural I/O controllers for controlling users and interfaces. CONSTITUTION:When users 1, 2 execute respectively independent two data processing by respectively using keyboards 1 connected to the I/O controller 3, mouses 2 and CRTs 4, the user 1 interrupts the controller 3 used by the user 2 and an instruction from the user 1 is displayed on the CRT 4 connected to the controller 3 used by the user 2 through a network controller 5. An instruction from the user 2 is similarly displayed on the CRT 4 connected to the controller 3 used by the user 1 through the controller 5. Since plural controllers 3 for controlling the users and the interfaces are connected, a program can be executed by the data processor while exchanging data between the plural I/O controllers.
