Subject: [PATCH] books/bookvolbib add Kupe14, N Queens on an FPGA
Goal: Axiom Literate Programming
This paper makes a principled transition from a mathematical
formulation of a problem to its reduction to executable code.

"This paper presents a design methodology for deriving an FPGA
implementation directly from a mathematical specification, thus
avoiding the switch in semantic perspective as is present in widely
applied methods which include an imperative implementation as an
intermediate step.
The first step in the method presented in this paper is to transform a
mathematical specification into a Haskell program. The next step is to
make repetition structures explicit by higher order functions, and
after that rewrite the specification in the form of a Mealy
Machine. Finally, adaptations have to be made in order to comply to
the fixed nature of hardware. The result is then given to
C$\lambda$aSH, a compiler which generates synthesizable VHDL from the
resulting Haskell code. An advantage of the approach presented here is
that in all phases of the process the design can be directly simulated
by executing the defining code in a standard Haskell environment.
To illustrate the design process, the N queens problem is chosen as a
running example."
