I need help with the following problems. Please do 4.5.1 and4.5.2, Thanks.
![4.5 For the problems in this exercise, assume that there are no pipeline stalls and that the breakdown of executed instructions is as follows: add addi notbeq lw SW 20% 20% 0% 25% 25% 10% 4.5.1 [10] <S4.3> In what fraction of all cycles is the data memory used? 4.5.2 [10] <4.3> In what fraction of all cycles is the input of the sign-extend circuit needed? What is this circuit doing in cycles in which its input is not needed?](https://d2vlcm61l7u1fs.cloudfront.net/media%2F8b9%2F8b9b51ce-67e6-49f5-9632-5afd702f350c%2FphpFyQnN3.png)
