BUYER ’ S GUIDE SOFTWARE AND DEVELOPMENT Ada 2005 for deeply embedded systems

The Ada 2005 standard features support for run-time profiles, flexible taskdispatching policies, execution-time clocks and timers, and a unification of concurrency and object-oriented features. Among these new facilities, one of the most significant is the standardization of the Ravenscar tasking profile. This subset of Ada tasking features embodies a deterministic concurrency model inherently amenable to static analysis and implementable by a small, reliable, and extremely efficient run-time library. The Ravenscar profile brings modern software engineering techniques to deeply embedded systems with limited resources by providing the abstraction and expressive power that help make software easier to design and test, but without compromising performance or safety.
