Consider the following instructions
STORE [10+r3],r1
Load r1, [20+r2]
ADD r1, r3
ADD r1, r2
Also, assume the following cycle times for each of the options related to forwarding:
Without Forwarding | With Full Forwarding | With ALU-ALU Forwarding only |
250ps | 300ps | 290ps |
For the above sequence of code complete the pipeline graph
- No Forwarding
- ALU-ALU Forwarding
- Full Forwarding
- Identify the stalls/NOP
