Abstract : Lucy-n is a data-flow programming language similar to Lustre extended with a buffer operator. It is based on the n-synchronous model which was initially introduced for programming multimedia streaming applications. In this article, we show that Lucy-n is also applicable to model Latency Insensitive Designs (LID). In order to model latency introduced by wires, we add a delay operator. Thanks to this new operator, a LID can be described by a Lucy-n program. Then, the Lucy-n compiler automatically provides static schedules for computation nodes and buffer sizes needed in shell wrappers.
