Measuring the real-time operating system performance

چکیده
Tests for measuring the real-time operating system performance belong to the software technology. They give quantitative measures for the most important characteristics and allow the implementer to compare the efficiency of various operating systems. This paper presents a set of simple tests for measuring the real-time operating system characteristics. The tests require no specialized hardware, and are based on direct measuring of the duration of execution of sequences of system functions. All tests described in the paper have been applied to measure the efficiency of a distributed operating system QNX. The measurements include the speed of intertask communication through messages, proxies and signals, and the speed of task switching and timer interrupt handling. The results are presented in a series of easily readable tables.

متن کاملDevelopment and Validation of Sound Transmission Loss Measurement System for Measuring Muffler Performance
Muffler is a part of the vehicle exhaust system that absorb or reflect sound waves to reduce exhaust noise. One of the most important determinants of a muffler performance is the amount of attenuation that has on its input wave; this parameter is known as sound transmission loss. Four - mic standard test is one way to determine this parameter which is used in this paper. In this study, a test d...
