Copilot: A (Haskell DSL) stream language for generating hard real-time C code.

Can you write a list in Haskell? Then you can write embedded C code using Copilot. Here's a Copilot program that computes the Fibonacci sequence (over Word 64s) and tests for even numbers:

fib :: Streams fib = do "fib" .= [0,1] ++ var "fib" + (drop 1 $ varW64 "fib") "t" .= even (var "fib") where even :: Spec Word64 -> Spec Bool even w = w mod const 2 == const 0

Copilot contains an interpreter, a compiler, and uses a model-checker to check the correctness of your program. The compiler generates constant time and constant space C code via Tom Hawkin's Atom (thanks Tom!). Copilot was originally developed to write embedded monitors for more complex embedded systems, but it can be used to develop a variety of functional-style embedded code.
