Consider the following instruction sequence executing on a 5-stage ARM pipeline with forwarding and hazard detection. Forwarding can be used to resolve the read-after-write hazards in executing the instruction sequence on the 5-stage pipelined microarchitecture. How does I3 obtain the value for the source operand R0?
