We execute the following instruction sequence (data hazards may exhibit in the sequence) on a MIPS 5-stage pipeline with forwarding and stall features implemented. Draw a graphical representation for the execution of the instruction sequence that clearly shows (1) forwarding path (if any); (2) stall cycles (if any); and (3) total cycles needed for the execution. lw R8, 0x0020(R10) add R9, R8, R10 sw R8, 0x0040(R10)

Assume that forwarding is not implemented and only the hazard
detection and stall logic is
implemented so that all data dependencies are handled by having the
pipeline stall until the
register fetch will result in the correct data being fetched.
