Q.1 - 4.6 from 5th edition (4.6.1, 4.6.2, 4.6.3 included)
Q.2 - 4.8 from 5th edition (4.8.1, 4.8.2, 4.8.3, 4.8.4, 4.8.6 included)
Q.3 -We wish to add the instruction addi (add immediate) to the singlecycle datapath described in the chapter. Add any necessary datapaths and control signals to the single-cycle datapath of the Figure 4.24 which represents the datapath and show the necessary additions (if any) to the Figure 4.18 which represents the setting of the control lines.
Q.4. - Assume that you are required to extend our single-cycle MIPS implementation so that it handles the “jnew” instruction, where “jnew” has R-type instruction format where rd field is 0. An example is given below:
Example: jnew $s3, $s4 # unconditionally jump to the address given in
Memory[$s3+$s4]
# PC← Memory[$s3+$s4]
Explain your design by listing the required changes in the complete single-cycle datapath clearly given in Figure 4.24 (additional wires, muxes and control and selector signals if necessary).
