What´s the frequency of work

Posted by Nobody/Anonymous on January 11, 2007
HI

I would like to undestand one thing in the scheduler.
The interrupt for the context switch or not happens periodicaly with certain frequency.

What is that frequency ? How do you define the Tick frequency it can´t be happening with top frequency because otherwise the processor would always be in the scheduler interrupt.

What´s the Tick frequency and how is it defined?

regards

Hi Again

So when in the Test results you have:

Scheduler tick function
66.2μs with optimization. 68.4μs with no optimization.

That is the time the secheduler takes to make the context switch between to threads running?

regards
