4. (10 pts) The following MIPS single-cycle datapath cannot perform BNE instruction. Indicate any changes to the datapath that must be done in order to support BNE instruction, e.g., adding extra wi extra logic gates, extra registers, etc. Do your modification on the following figure if necessary, and show the dataflow for t the corresponding control signals in the following table and add new control signals to his instruction using dash lines on the modified figure.
