Consider the following sequence of instructions: (I1) beq $9, $10, EXIT (I2) add $9, $11, $12 (I3) lw $16, 12($9) (I4) sw $16, 16($19) (I5)
Consider the following sequence of instructions:
(I1) beq $9, $10, EXIT
(I2) add $9, $11, $12
(I3) lw $16, 12($9)
(I4) sw $16, 16($19)
(I5) sw $18, 0($11)
(I6) add $4, $0, $0
(I7) add $5, $0, $0
Assume the following:
- There are no stalls in the code above
- 5 stage pipeline (IF, ID, EX, MEM, WB) is available
- Each instruction executes every stage
- No branch stalls
- Draw the pipeline stage table and identify instructions and stages in the table.
- What is the Pipeline Instructions Latency?
- What is the Pipeline Instructions Throughput?
- What is the Pipeline Instructions Concurrency? For the same code Assume the following:
- There are no stalls in the code above
- 5 stage pipeline (IF, ID, EX, MEM, WB) is available
- Stages IF, ID, and EX take 100 ps, MEM takes 200 ps, and WB takes 150 ps
- Each instruction executes every stage
- No branch stalls
