Abstract :
This paper describes a real-time response of UNIDAQ. Interrupt task response time and task switching (context switching) time are measured for real-time UNIX (LynxOS) systems and standard UNIX systems. Here we show the correlation between the context switching time and the values of a benchmark program, SPECint92. We also show distributions of the response time for various operating systems (OS). A performance evaluation tool, DAQBENCH, was used for the measurements.
