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