Commentary: Measuring the performance in real time

Measuring Execution Time and Real - Time Performance

Many embedded systems require hard or soft real-time execution. To ensure the requirements are met, it is necessary to measure the execution time of individual tasks, as well as establish the overall real-time performance of the system. This paper presents a variety of techniques, at both coarse-grain and fine-grain levels, to measure execution time of both user code and operating system overhe...

Measuring the real-time operating system performance

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,...

Measuring Signalized Intersection Performance in Real-Time With Traffic Sensors

Safety and quality of travel on arterial networks tie closely to the performance of signalized intersections. Measures commonly used for intersection performance evaluations are control delay, queue length, and cycle failure. However, these variables are not directly available from typical configurations of traffic sensors designed for intersection signal control. Collecting vehicle control del...

Measuring Real-time Performance in Distributed Object Oriented Systems

The principles of distributed object oriented programming o er great possibilities for exible architectures in multiple elds. In telecommunications, an architecture called Telecommunication Information Networking Architecture (TINA) has been developed using these very principles. It allows telecommunication services to be implemented using software objects that in turn can be executed in a loca...
