(ii) Demonstrate two valid instructions of the machine; put some valid data values in registers and memory locations and show these two instructions.

 Let's consider two instructions for the given machine, assuming the following:

Data Values:

- Assume data values stored in registers R1 and R2.

- Assume a data value stored in memory location M1.

Instructions:

1. Instruction to Add Register Contents:

   - Operation Code (Op Code): 0100110 (Assume opcode for addition)

   - Memory Operand: Unused (0000000000000000)

   - Register Operand 1 (Source): R1 (0000000000000001)

   - Register Operand 2 (Destination): R2 (0000000000000010)

   Binary Representation:

   ```

   0100110 0000000000000000 0000000000000001 0000000000000010

   ```

   Explanation:

   - This instruction adds the contents of registers R1 and R2 and stores the result in register R2.

2. Instruction to Load Data from Memory to Register:

   - Operation Code (Op Code): 1101011 (Assume opcode for memory load)

   - Memory Operand: M1 (0000000000000011)

   - Register Operand (Destination): R1 (0000000000000001)

   - Unused: 0000000 (7 unused bits)

   Binary Representation:

   ```

   1101011 0000000000000011 0000000000000001 0000000

   ```

   Explanation:

   - This instruction loads the data from memory location M1 into register R1.

These examples illustrate the binary representation of instructions based on the designed format. The specific operation codes and values are assumed for demonstration purposes, as the actual values would depend on the machine's instruction set architecture.
