A multiprocessor multiwindow parallel visualization subsystem is presented which can be hooked onto parallel processor arrays of high-speed network interfaces. Thanks to its well-balanced triple transputer architecture, the multiwindow display subsystem is capable of simultaneously transferring, clipping and displaying 24bit/pixel colour images at a rate of 18 Mbytes/s. Under optimal conditions it is able to receive, clip and display six full-screen 1024×1024 or twenty-four 512×512 full-colour images/s. Such a display subsystem is one order of magnitude faster than X-window systems running on standard workstations. It satisfies the need for browsing through image databases and for fast visualization of uncompressed image sequences
