Abstract
Streaming dataflow designs describe hardware by connecting components through streams that transport data structures. We introduce a stream-oriented specification and type system that provides a clear and intuitive way to map complex, dynamically-sized data structures onto hardware streams. This helps designers to lift the abstraction of streaming dataflow designs, reducing the design effort. The type system allows complex data structures to be as easy to use in streaming dataflow designs as in modern software languages today.
