Hi,

I want to measure eCos multi-threading energy costs. I use it on the
assabet board.
In order to measure context switch overhead, I need some infos about
timeslicing:

- the option CYGNUM_KERNEL_SCHED_TIMESLICE_TICKS refers to 3.6864MHz
    clock ticks?

- How does eCos use real time clock (RTC) and operating system timer
(OSCR) of
    StrongARM 1110?

Andrea.
