Re[Haskell-cafe] targeting Haskell compiler to embedded/hardware

If you are really interested in embedded realtime code you may want to have a
look at the timber language[1] or bit-c[2]. Another very interesting project
is this[3] developing a new Haskell like language called Habit for systems

There are also some great papers about systems programming and problems in
Haskell. For example "Strongly typed memory areas programming systems-level
data structures in a functional language".
