<p>PURPOSE:To dynamically change the number of buffer planes by classes by changing buffer control information by classes on buffer control areas by classes so as to be synchronized with the real plane number of buffers by classes. CONSTITUTION:A definition changing means 4 for the number of buffer planes turned on from an exclusive terminal for a system manager while operating a system changes buffer control information on buffer control areas 2 by classes so as to synchronize it with the really secured plane number of buffers by classes, and the plane number of buffers by classes is dynamically changed in this system. Thus, the plane number of buffers by classes can by dynamically changed for efficiently managing the buffers by classes corresponding to various conditions.</p> |
