Methods of assessing the time efficiency in the virtual measurement systems

The paper presents the analysis of the time measurement methods in the virtual instrumentation. Problem of the software operations time efficiency assessment is presented. Different methods and functions of the time measurement in the integrated programming environments are discussed. Experiments using the exemplary virtual instrument are conducted to reveal the advantages and disadvantages of particular time measurement methods. Both general purpose and Real-Time operating systems are considered. Experiments cover personal computers, and specialized systems, such as CompactRIO. Conclusions include the analysis of the possible approaches to the time-efficient instrument design and future applications of the presented methods.

► Comparative analysis of the time measurement functions.
► Analysis of the software behavior under General Purpose Operating System and Real-Time Operating System.
► Proposal of the time analysis methodology for various systems (personal and industrial computers).
