Abstract

This paper presents a new method for deriving path and loop annotations automatically for object-oriented real-time programs. Such annotations are necessary when the worst case execution time (WCET) of programs is to be calculated. Normally these annotations must be given manually by the programmer.By automating the the generation of annotations the user is relieved from a task that can be quite difficult and highly critical. If, for example, a programmer gives a too optimistic annotation for a loop, a tool may calculate a too short WCET. This may invalidate subsequent analysis, leading to that a real-time system may violate its real-time properties.The method is based on the notion of abstract interpretation, and is illustrated by showing the analysis of an example in Smalltalk.The paper also discusses alternatives to the semantic analysis used in the method. It is shown that syntactic analysis suffices in some cases, and that it can be used to reduce the calculation cost for loops.
