Starting with the single cycle implementation of ANNA discussed in class, make necessary modifications to support the jalr instruction. You cannot modify the ALU, register file, or either memory. The other twelve instructions must work in the modified datapath. (10+10) A. Your changes may include but are not limited to: Adding a mux. Indicate where the mux is located, the inputs to the mux and define a control line. Adding an input to existing mux. Indicate the mux that you are adding the control line. Add the new input to the bottom (highest value) of the mux. Modifying or adding combinational logic. Potential targets include the branch detection unit, the extension units, and the logic needed to compute the target address. Describe any changes you make in this regard. I have done some work for you by providing the following skeleton. Fill in the blanks below to complete the implementation: B. List the value for each control signal in the ANNA processor when executing the jalr instruction.
