This paper describes a new approach towards a component architecture for hard real time control applications as found, for example, in the automotive domain. Based on the paradigm of Logical Execution Time (LET) as introduced by Giotto [1], we adapt the high-level language construct
module
which allows us to organize and parallelize real time code in the large. Our module construct serves multiple purposes: (1) it introduces a namespace for program entities and supports information hiding, (2) it represents a partitioning of the set of actuators and control logic available in a system, (3) it acts as a static specification of components and dependencies, (4) it may serve as the unit of dynamic loading of system extensions and (5) it may serve as the unit of distribution of functionality over a network of electronic control units. We describe the individual usage cases of modules, introduce the syntax required to specify our needs and discuss various implementation aspects.
