Q2-ii

Using an expanding opcode encoding for instructions, is it possible to encode all of the following in an instruction format shown in the below figure. Justify your answer.

$$\begin{array}{ll} \text{14} & \text{double address instructions} \\ \text{127} & \text{single address instructions} \\ \text{60} & \text{no address (zero address) instructions} \\ \end{array}$$ $$\begin{array}{|c|c|c|} \leftarrow4\text{ bits}\rightarrow& \leftarrow6\text{ bits}\rightarrow & \leftarrow6\text{ bits}\rightarrow \\ \hline \text{Opcode}& \underset{\text{Address}}{\text{Operand 1}}& \underset{\text{Address}}{\text{Operand 2}} \\\hline \end{array}$$
