✦ Synopsis

There is evidence that, among all design domains of hard real time systems, architectural issues gained the lowest research interest. Universal architectures, which are generally applied as hardware bases for hard real time applications, are seldom behaving in a fully predictable way. In the paper, several commonly used techniques which prevent temporal determinism of instruction execution are enumerated. An asymmetrical multiprocessor architecture for hard real time applications is presented, whose temporal behaviour is fully predictable. Some adequate features are discussed which are incorporated into the processor's implementation.
