Abstract : We study scheduling of structured systems of recurrence equations. We first recall the formalism of structured systems of recurrence equations, then we explain how to implement a scheduling tool for non-structured systems of reccurence equations. We introduce the notion of structured schedule and propose criteria for determining whether a structured system of reccurence equations admits a structured schedule. We give an algorithm for its computation. Finaly we propose an algorithm for computing structured multi-dimensionnal schedule for systems which do not admit a structured linear schedule. With this last method, we derive a structured schedule for a structured system of recurrence equations computing the singular value decomposition of a matrix.
