Berkeley UNIGRAFIX is a graphics system that runs under the UNIX operating system. It comprises a collection of rendering programs and scene generating programs. Scenes of objects are described in a terse, human-readable format called the UNIGRAFIX descriptive language. In order to display parametric curves and surfaces using UNIGRAFIX, we developed a scene generator called UGTRACE. It traces a set of parametric equations and generates a scene file written in the UNIGRAFIX format. Two tracing modes as well as two displaying modes were designed. The Berkeley UNIGRAFIX system was installed in the McMaster environment. For our purpose, we also modified the various device drivers of UGDISP, the latest version of the renderers. Available output devices include the AED colour graphics terminal, the IMAGEN laser printer and the IBM PC emulating a Tektronix 4010 terminal. UGDISP is used to display scene files generated by UGTRACE. / Thesis / Master of Science (MSc)

International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / In this paper we describe the design of the REAL/STAR 2000 system, a highperformance real-time computer for telemetry applications. The REAL/STAR 2000 is a symmetric, tightly-coupled multiprocessor, optimized for real-time processing. The system provides a high level of scalability and flexibility by supporting three configurations: single, dual, and quad processor configurations, based on Motorola 88100 RISC processors. The system runs the multiprocessor REAL/IX operating system, a real-time implementation of the AT&T UNIX System V. It compiles with BCS and OCS standards, meets the POSIX 1003.1 standard, and has the current functionality of the emerging POSIX 1003.4 real-time standard. The REAL/STAR 2000 promotes an open system approach to real-time computing by supporting major industry standards. Benchmark results are also presented in the paper.
