%X ClaSH, a functional hardware description language based on
   Haskell, has several abstraction mechanisms that allow a
   hardware designer to describe architectures in a short and
   concise way. In this paper we evaluate ClaSH on a complex
   DSP application, a Polyphase Filter Bank as it is used in
   the ASTRON APERTIF project. The Polyphase Filter Bank
   is implemented in two steps: first in Haskell as being close
   to a standard mathematical specification, then in ClaSH
   which is derived from the Haskell formulation by applying
   only minor changes. We show that the ClaSH formulation can
   be directly mapped to hardware, thus exploiting the
   parallelism and concurrency that is present in the
   original mathematical specification.
