Báo Cáo Evaluation of real time performance of embedded linux

ABSTRACT
​

Nowadays, embedded systems with Linux OS are commonly applied in automotive
industry. Some of applications require strict time response, and others need to be exactly
scheduled to execute a period task. All of these are called time-sensitive applications. Measuring
and evaluating time parameters of an embedded system for time-sensitive applications is very
necessary for developers to guarantee that it works functionally. For this purpose, signal
stimulating and signal analyzing hardware are required. In this paper, modular signal generating
and signal analyzing means will be designed. The prototype of the evaluation system will be
implemented to test and verify an embedded system.

Improving the performance of the system is the next part of this report. The research focuses
deeper on the possibility of turning Linux into a real-time operating system. Particularly, it
investigates available real-time solutions for Linux, but also looks into the soft variants for
completeness. A number of performance tests are conducted during the improvement to make
sure that the implementation meets the demands of a real-time operating system.
