For the problems in this exercise, assume that there are no pipeline stalls and that the breakdown of executed instructions is as follows: 1. In what fraction of all cycles is the data memory used? 2. In what fraction of

For the problems in this exercise, assume that there are no pipeline stalls and that the breakdown of executed instructions is as follows:

addi not add beq Iw SW 20% 20% 0% 25% 25% 10%

1. In what fraction of all cycles is the data memory used?

2. 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?

For the problems in this exercise, assume that there are no pipeline stalls and that the breakdown of executed instructions is as follows: 1. In what fraction of all cycles is the data memory used? 2. In what fraction of

addi not add beq Iw SW 20% 20% 0% 25% 25% 10%

This problem has been solved!

1. The data memory is used by LW and SW instructions, so the answer is: 25% + 10% = 35% 2. Th…View the full answer
