So the answer should be $9$ right? $(k+n-1)\times T_p=(5+5-1)\times 1=9\:clock\: cycles.$ 0 votes 0 votes Abhishek3301 commented Dec 9, 2023 reply Follow Share I made a similar mistake, but I've identified the error. The correct answer is 10. 0 votes 0 votes Please log in or register to add a comment.
Best answer 1 votes 1 votes (K + n - 1) = 5 + 5 - 1 = 9. 1 extra cycle due to data dependency between I2 and I3. Operand forwarding can only solve data dependancy between ALU to ALU Hence, 9 + 1 = 10.

Can you share the resource from where you read about this condition on operand forwarding? 0 votes 0 votes Abhishek3301 commented Dec 9, 2023 reply Follow Share https://www.youtube.com/live/9t4wsNlfXD4?si=7u16B0LD2XcYxUl5&t=3929 1 votes 1 votes Please log in or register to add a comment.
