RTL/RTAI work fine with fpu provided you inform RTL/RTAI RTL: call rt_task_use_fp(&task, 1) RTAI: call rt_linux_use_fpu(1) and set argument 6==1 when calling rt_task_init There are some RTL/RTAI examples at: http://www.realtimelinux.org/CRAN/examples/rtexamples.tar.gz If you look at the sinewave example it shows the use of fpu.
