Ramesh We propose a simple programming language called Nemo specific to the domain of multitask real-time control systems such as in robotic automotive or avionics systems. It can be used to specify a set of resources with usage constraints a set of tasks that consume them according to various modes and applications sequencing the tasks. We automatically obtain an applicationspecific task handler that correctly manages the constraints if there exists one through a compilation-like process including a phase of discrete controller synthesis. This way this formal technique contributes to the safety of the designed systems while being encapsulated in a tool that makes it usable by application experts. Our approach is based on the synchronous modelling techniques languages and tools. Copyright 2007 G. Delaval and E. Rutten.

CONTEXT AND MOTIVATION 1.1. Embedded control systems Embedded control systems are implementing automatic control laws or signal processing such as in robotic automotive or avionics systems or even more widely available portable devices processing voice and image signals. These systems are reactive working in close interaction with their environment including the controlled process which has its own dynamics typically following the laws of .
