Synchronous functional languages à la Lustre are high-level equational formalisms dedicated to the design and implementation of real-time systems. Their compilers produce finite-state imperative code from pure stream transformers. These languages have traditionally been restricted to critical systems with low computational demand; in particular, the generated code does not usually feature loops.

Lucy-n is a recent derivative of Lustre tailored to multimedia processing. In this talk, I will describe an extension of Lucy-n where streams transport vectors of values rather than scalars, and a type system characterizing the size of these vectors. The code generation process then produces nested loops in a type-directed manner.
