It is mentioned by an article on LinuxDevices.com

As far as my C-knowledge goes, I don't see any explicit assembler code
in this file. But I might be wrong.

As I could see, the benchmark is written for x86 (well, if you take a
look at the Makefile, you might suspect it). I hoped it would

If there are other benchmarks for RTAI on PPC, please tell me. It saves
