Preliminary definition of CORTEX programming model

Technological advances will allow the integration of smart devices which may comprise sensor components, computational devices and a network interface. The built-in computational component enables the implementation of a well-defined high level interface that does not just provide raw transducer data, but a pre-processed, application-related set of process variables. The paper deals with two issues. Firstly, it describes an architecture which encourages the design of multi-level control hierarchies exploiting the easy availability of application related sensor information. This is based on encapsulated smart components, a well defined communication interface and the easy access to this information by a variant of a shared data space. Secondly, we describe the functions and the hardware of ICU which constitutes the prototype of an optical sensor designed for vehicle guidance operating as a smart component in such a system. The task of the sensor is to detect a guidance line and directly produce the information needed by the steering system to control the vehicle.
