The following MIPS code is executed on a 5-s forwarding stage pipelined processor with full (b) [8 pts] Complete the pipeline execution diagram of the new code sequence for the first 17 cycles and indicate the data forwarding. Please indicate the forwarding using the format [cycle number][pipeline register name] [cycle number][Pipeline stage], e.g. 9EXMEM9EX means that the data is forwarded from the EXMEM pipeline register at cycle 9 to the EX stage at cycle 9. The execution of the first instruction has been given as an example. You do not need to show the execution of NOP instructions.
