1. Suppose the machine language described in Appendix C has been extendedas suggested at the end of this section. Moreover, suppose register 8 containsthe pattern DB, the memory cell at address DB contains the pattern CA, andthe cell at address CA contains the pattern A5. What bit pattern will be inregister 5 immediately after executing each of the following instructions?a. 25A5b. 15CAc. D5082. Using the extensions described at the end of this section, write a completemachine language routine to perform a pop operation. Assumethat the stack is implemented as shown in Figure 8.12, the stack pointeris in register F, and the top of the stack is to be popped into register 5.3. Using the extensions described at the end of this section, write a programto copy the contents of five contiguous memory cells starting ataddress A0 to the five cells starting at address B0. Assume your programstarts at address 00.4. In the chapter, we introduced a machine instruction of the form DR0S.Suppose we extended this form to DRXS, meaning "Load register R with thedata pointed to by the value in register S plus the value X." Thus the pointerto the data is obtained by retrieving the value in register S and then incrementingthat value by X. The value in register S is not altered. (If register Fcontained 04, then the instruction DE2F would load register E with the contentsof the memory cell at address 06. The value of register F wouldremain 04.) What advantages would this instruction have? What about aninstruction of the form DRTS—meaning "Load register R with the datapointed to by the value in register S incremented by the value in register T"?
