Invasive computing is a novel computing paradigm, which allows us to allocate several resources at run-time. Tightly-coupled processor arrays are well suited for invasive computing. This paper proposes a methodology, to symbolically program a claimed array of computational resources. Using this methodology, a single configuration stream can be derived, which is sufficient to configure all the claimed resources (processing elements) irrespective of the number of resources claimed. The configuration stream is modified at run-time dynamically, depending on the number of processors claimed. Configuration memory requirements were estimated for our methodology. It requires constant memory size and is independent of the problem size compared to a traditional approach.
