Abstract: Sub-project 2 has as its major objective the definition of an abstract model that supports the project’s goals of self-adaptation at all levels within a system, from the hardware to the application layer. Moreover it must provide a firm definition of a realisation of that model that will eventually enable the development of various prototype tools to support the model at each of these levels. In particular that realisation must provide a compiler target for the work in SP3 and also support various implementation paradigms. The abstract model may be implemented in hardware, software or both. These implementations will range from programming conventional processors through to synthesising configurations of hardware using various reconfigurable architectures. In order to meet this goal, a thread-based model has been adopted in which the threads may range from single machine operations through to complete programs and in which the unit that supports the goal of self-adaptation is not the single thread, which may just define a machine operation, but the abstraction of a family of related threads. This abstraction captures concurrency, locality, communication, synchronisation as well as more the abstract notions such as mission requirements and resource definitions. Both the model and its realisation have been developed and defined in internal working documents. Substantial progress has been made in defining interfaces to both higher-level work in SP3 and some in the directions required in defining interfaces in the lower-level work in SP1.
