Giotto: A time-triggered language for embedded programming. (English) Zbl 1050.68525

Henzinger, Thomas A. (ed.) et al., Embedded software. 1st international workshop, EMSOFT 2001, Tahoe City, CA, USA, October 8–10, 2001. Proceedings. Berlin: Springer (ISBN 3-540-42673-6). Lect. Notes Comput. Sci. 2211, 166-184 (2001).
Summary: Giotto provides an abstract programmer’s model for the implementation of embedded control systems with hard real-time constraints. A typical control application consists of periodic software tasks together with a mode switching logic for enabling and disabling tasks. Giotto specifies time-triggered sensor readings, task invocations, and mode switches independent of any implementation platform. Giotto can be annotated with platform constraints such as task-to-host mappings, and task and communication schedules. The annotations are directives for the Giotto compiler, but they do not alter the functionality and timing of a Giotto program. By separating the platform-independent from the platform-dependent concerns, Giotto enables a great deal of flexibility in choosing control platforms as well as a great deal of automation in the validation and synthesis of control software. The time-triggered nature of Giotto achieves timing predictability, which makes Giotto particularly suitable for safety-critical applications.
