Language X provides a formal and intuitive way to describe a series of interconnected processing ﬁblocks.ﬂ Users of Language X may enter in a logical arrangement of blocks that describes the interconnection of their inputs and outputs. Language X also provides syntax for specifying implementation details for processing blocks and for targeting the entire architecture onto arbitrary sets of devices. Formally, Language X is a structure-only dataflow programming language (DFPL) that is heavily dependent on its library of functions.
