RESUMO

Critical Real-Time Systems are becoming more used each day. The great complexity in creating real-time applications favors the sprouting of new resources that facilitate the designer to adapt such systems to his/her needs. Among them there are the Real-Time Operating Systems (RTOS). A consequence of this is that RTOS adoption have significantly increased, mainly among those that are based on General Purpose Operating Systems (GPOS), more specifically the ones that are based on Linux. There are also systems that have been developed specifically for the treatment of temporal tasks: one of the most famous are the VxWorks by Wind River and Windows CE from Microsoft. However the RTOS is an integral part in a real-time system. The present work tries to facilitate the designer of real-time system to choose from some well known RTOS, among them the one developed by Microsoft, Windows CE and the source system open RTLinux and RTAI. Key elements, as predictability, size, modularity and adaptability are verified and compared in order to assist the designer in the development of more reliable systems. The final result will be the verification of the real capability and maturity of such RTOS, assisting in the creation of real-time systems. Also the scheduler of each system is analyzed concerning its modification flexibility
