I think this is a supported BSP but I am not sure. So changing the
subject to attract someone who might answer definitively.
What specifically do you plan to do? Comparing RTOSes is difficult
since you have to be careful you are doing the same operations with
Also simply the scope of what is implemented impacts performance.
We have very full featured mutexes which not surprisingly are slower
than simple, minimal implementations without features like Priority
Inheritance or Ceiling Protocols.

Everything is on the web. There are some published papers but nothing
as general as what is there.
Anything specific you want?
