I'd be strongly tempted to do a clean implementation of the bits of the
scheduler you're interested in based on the descriptions of the
algorithms in the paper. Having had another look at the CCSP code, I
think this route'll be less effort than trying to extract just the
scheduling code from CCSP; it would also have the side benefit of
validating that our published description of the scheduler is complete.

Do you have a multicore embedded platform in mind to do this on?  If so,
check whether it's got a C++11 compiler that supports the new atomic
primitives; this'll save you some work in (and be more portable than)
implementing your own.
