PERFORMANCE MEASUREMENTS OF REAL-TIME COMPUTER SYSTEMS

International Telemetering Conference Proceedings / October 29-November 02, 1990 / Riviera Hotel and Convention Center, Las Vegas, NevadaThe performance of general purpose computers is typically measured in terms of Millions of Instructions per Second (MIPS) or Millions of Floating-Point Operations per Second (MFLOPS). Standard benchmark programs such as Whetstone, Dhrystone, and Linpack typically measure CPU speed in a single-task environment. However, a computer may have high CPU performance, but poor real-time capabilities. Therefore there is a need for performance measures specifically intended for real-time computer systems. This paper presents four methodologies, related metrics and benchmarks for objectively measuring real-time performance: (a) Tri-Dimensional Measure, (b) Process Dispatch Latency Time, (c) Rhealstone Metric, and (d) Vanada Benchmark. This proposed methodologies and related measures are applied in the performance evaluation of several real-time computer systems, and the results obtained are presented.International Foundation for TelemeteringProceedings from the International Telemetering Conference are made available by the International Foundation for Telemetering and the University of Arizona Libraries.
