On synchronization in hard-real-time systems
Stuart R. Faulk, David Lorge Parnas · Communications of the ACM · 1988
The design of software for hard-real-time systems is usually difficult to change because of the constraints imposed by the need to meet absolute real-time deadlines on processors with limited capacity. Nevertheless, a new approach involving a trio of ideas appears to be helpful for those who build software for such complex applications.
