+  In addition to looking at designing a hardware description language, we

+  translate hardware descriptions written in the Haskell functional language
+  to simple (netlist-like) hardware descriptions in the \VHDL language. The
+  reasons for choosing these languages are detailed in section
+  \in{}[sec:prototype:input] and \in{}[sec:prototype:output] respectively.

 In the first chapter, we will sketch the context for this research.
