The Design and Implementation of Feldspar: an Embedded Language for Digital Signal Processing
Övrigt konferensbidrag, 2010

Feldspar is a Domain Specific Language, embedded in Haskell, for programming Digital Signal Processing algorithms. The final aim of a Feldspar program is to generate low level code with good performance. Still, we chose to provide the user with a purely functional DSL. The language is implemented as a minimal, deeply embedded core language, with shallow extensions built upon it. This paper presents full details of the essential parts of the implementation. Our initial conclusion is that this approach works well in our domain, although much work remains.
