dc.description.abstractA special feature of the occam programming language is that its concurrency support is at the very base of the language. However, its ability to specify scheduling requirements is insufficient for use in some real-time systems. Toc is an experimental programming language that builds on occam, keeping occam's concurrency mechanisms, while fundamentally changing its concept of time. In Toc, deadlines are specified directly in code, replacing occam's priority constructs as the method for controlling scheduling. Processes are scheduled lazily, in that code is not executed without an associated deadline. The deadlines propagate through channel communications, which means that a task blocked by a channel that is not ready will transfer its deadline through the channel to the dependent task. This allows the deadlines of dependent tasks to be inferred, and also creates a scheduling effect similar to priority inheritance. A compiler and run-time system has been implemented to demonstrate these principlesnb_NO
