  abstract=      "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."
