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???
