Title Applying Unifying Theories of Programming to Real-Time Programming
Abstract This paper introduces an approach to verify the correctness of the implementation of real-time languages. We apply the techniques presented in Hoare and He's Unifying Theories of Programming to reason about the correctness of compilers and schedulers for real-time languages, using high-level abstractions such as algebraic laws. In the compilation process, the existence of unique fixed-points is exploited to verify the implementation of crucial real-time operators such as asynchronous input, delay and timeout. It is developed an abstract model for scheduling real-time programs into a uniprocessor machine. The applicability of the model is shown by instancing it with two types of schedulers: a round-robin scheduler, employed when the participating parallel processes do not include deadline constraints, and a priority-based scheduler, used when each participating process is periodic and possesses an associated deadline.
