Abstract: A computer display (40) has a display processor (41) connected to a presentation space buffer (50) and a screen buffer (70). The presentation space buffer is larger than the screen buffer, and is divided into a plurality of partitions. Each partition has a partition window which maps into the screen buffer. If a partition is active, its associated partition window is written into the screen buffer at the mapped location. The screen buffer periodically refreshes the display screen, so a plurality of partition windows are displayed to the computer user. One or more scroll groups can be defined, and one or more partitions can be assigned to each scroll group. Each defined scroll group has a vertical scroll trigger and a horizontal scroll trigger. The display monitors the movement of the cursor within a partition window. When the cursor gets close enough to a boundary of a partition window, to trigger a scroll trigger, the display shifVYts the partition window within its partition and writes this updated partition window into the screen buffer. Updated partition windows are written into the screen buffer for the other partitions in the scroll group.

Abstract: A system for supporting graphics display sessions on remote terminals contains a processing subsystem dedicated to graphics support. Applications execute on a central processor (44), and display related graphics commands are executed on the separate graphics controller subsystem (48). The graphics subsystem is preferably connected to multiple remote terminals over a network, and communicates with them without requiring all work to be performed by the central processor which is executing the applications.
