Classify each of the following instructions (in the machine language of Appendix C) in terms of whether its execution changes the contents of the memory cell at location 3B, retrieves the contents of the memory cell at location 3C, or is independent of the contents of the memory cell at location 3C.
a. 353C
b. 253C
c. 153C
d. 3C3C
e. 403C

Classifying the following instructions in terms of whether its execution

• Changes the contents of the memory cell at location 3B

• Retrieves the contents of memory cell at location 3C

• Independent of the contents of the memory cell at location 3C

a. 353C

This instruction would cause the contents of register 5 to be places in the memory cell whose address is 3C.

So this instruction is independent to the contents of memory cell at location 3C.

b. 253C

This instruction would cause 3C to be placed in register 5, so this instruction is independent of contents of the memory cell at location 3C.

c. 153C

This instruction causes the contents of memory cell located at address 3C to be placed in register 1. So the instruction retrieves the contents of the memory cell at location 3C.

d. 3C3C

This instruction would cause the contents of register C to be placed in memory cell whose address is 3C. So this instruction is independent of the contents of the memory cell at location 3C.

e. 403C

Move the bit pattern found in 3 to be copied in register C. So this instruction is independent of the contents of memory cell at location 3C.
