The Ravenscar profile is a subset of the Ada 95 tasking model: it is certifiable, deterministic, supports schedulability analysis, and meets tight memory constraints and performance requirements. A central feature of Ravenscar is the use of protected objects to ensure mutually exclusive access to shared data. We give a semantics to protected objects using Circus, a combination of Z and CSP, and prove several important properties; this is the first time that these properties have been verified.
more &raquo; ... nterestingly, all the proofs are conducted in Z, even the ones concerning reactive behaviour.
