Asynchronous interrupts abound in computing systems, yet they remain a thorny concept for both programming and verification practice. The ubiquity of interrupts underscores the importance of developing programming models to aid the development and verification of interrupt-driven programs. The research reported here recognizes asynchronous interrupts as a computational effect and encapsulates them as a building block in modular monadic semantics. The resulting modular semantic model can serve as both a guide for functional programming with interrupts and as a formal basis for reasoning about interrupt-driven computation as well.
