Abstract

This paper describes the calculation of execution times in RealTimeTalk (RTT). RTT is an object-oriented language for hard real-time systems, i.e., systems which must fulfil the specified time requirements. An overview of RTT is given. The control structures in RTT are analysed and equations for the calculation of minimum and maximum execution times are given. The RTT timing analysis tools are described. The first tool is the front-end tool, which analyses the RTT code given by the user. The second is the back-end tool, which analyses the C-code and the assembly code in the RTT system. Some limitations of the method and future directions are discussed
