How to measure task context switching time

1,104 Views

Hi,

I'm using uCos-II on Altera DE2 board, and I want to measure a context switching time between two tasks.

I tried to use a timestamp function to measure the time, but unfortunately it is not working well.

What are the functions that are called during context switch (OS_Sched() and ..?) ?

I'd be very grateful if anyone can help on this :)
