Part A: We wish to add the datapath parts and control needed to implement the jal (jump and link) instruction. Show the additions to the datapath and control lines of the figure enclosed (Figure 1 below) needed to implement these instructions in the multicycle datapath. There are multiple solutions; choose the solution that minimizes the number of clock cycles for the jal instruction.
Part B: Show the additions to the finite state machine of Figure 2 below to implement the jal instruction.

Question 4: Single Cycle Datapath Control (15 points) We wish to add the hardware support for a special R-type instruction jlr Jump and Link Register) to the single-cycle datapath below. Though this is an R-type instruction, but it is a special one that has the opcode being 000001 (instead of 000000), so the control unit will be able to differentiate this jlr instruction from the other R-type instructions and generate a special set of controls for this instruction. Opcode rs...

Modify the circuit to support a MFCC instruction. MFCC Rd instruction: Move From Condition Codes MFCC copies into the four rightmost bits of Rd the values of the ALU signals Carry (C), Overflow (O), Zero (Z) and Negative (N) as they were set by the previous R- type instruction. The remaining 28 bits of Rd are set to zero. Describe the changes and additions needed for the single-cycle MIPS processor datapath and control to support this instruction. Hints: 1) MFCC...
