Multitransputer graphics subsystem

Abstract Most recent graphics workstations implement graphics accelerators based on dedicated VLSI chips. The paper proposes a modular architecture using transputers and flexible software routines. A set of transputers with a crossbar connection scheme prepares the drawing. Another set using video RAMs controls a high-resolution colour monitor, each transputer handling a strip on the screen and a colour. Performance using straightforward C routines is 900 trapezoids per second per transputer. The flexible architecture allows the number of transputers to be adapted to the performance required.
