Total: n instruction Total conditional statement probability :p and True condition probability:q

i)Branch is known at end of t satge

Effective CPI = [npq*(t+1) + (n-npq)*1)]/n

OR

ii) Penality  is t stall cycle

  same i.e Effective CPI = [npq*(t+1) + (n-npq)*1)]/n

OR
iii)  

Effective CPI= 1+ stall freq*stall penality

=1+pq*t

am i correct???
