Hackage :: [Package]

copilot: A lazy-list language for generating constant-time and constant-space C programs. Uses Atom as a backend.

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.

Readme for copilot-0.21

[back to package description] 
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.
