Abstract :
Time-sensitive objects (TSO), a data-oriented model for real-time systems, impose timing constraints on object values using validity intervals and object histories. Periodic objects, a class of objects within the TSO model, are described in detail and compared with more traditional periodic processes. Advantages of periodic objects are identified, including greater scheduling independence of processing related through data dependencies, more opportunity for concurrency, and improved structure for timing fault tolerance
