sir,
 Thks a lot.
  still try too hard to find the execution time for  a process.
 My question is 
  "a processor will have certain processes to do.Before doing any
process it will have scheduling algorithm to do that.For that it
should know the execution time for the process.How a process will know
the execution time of the process"
My guess is
 "for calculating the exec. time for a process the cpu should
interpret the instruction & should calculate the time or cycles of
process."

is it so?
Please help me .
