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.
