Solution

The final values stored in 2and2 and 3 are 0x40 and 0x32 respectively.

Here's the step by step explanation:

  1. addi 2,2, 0, 0x42: This instruction adds the immediate value 0x42 to the value in register 0(whichisalways0),andstorestheresultinregister0 (which is always 0), and stores the result in register 2. So, $2 = 0x42.

  2. addi 3,3, 0, 0x42: This instruction does the same as the previous one, but stores the result in register 3.So,3. So, 3 = 0x42.

  3. andi 2,2, 2, 0xF0: This instruction performs a bitwise AND operation between the value in register 2(0x42)andtheimmediatevalue0xF0.Theresultis0x40,whichisstoredbackin2 (0x42) and the immediate value 0xF0. The result is 0x40, which is stored back in 2.

  4. andi 2,2, 2, 0xF0: This instruction does the same as the previous one. Since the value in $2 is already 0x40, the result remains 0x40.

  5. xori 3,3, 3, 0xF0: This instruction performs a bitwise XOR operation between the value in register 3(0x42)andtheimmediatevalue0xF0.Theresultis0xB2,whichisstoredbackin3 (0x42) and the immediate value 0xF0. The result is 0xB2, which is stored back in 3.

  6. xori 3,3, 3, 0xF0: This instruction does the same as the previous one. Since the value in $3 is now 0xB2, the result of the XOR operation is 0x42.

So, the final values are 2=0x40and2 = 0x40 and 3 = 0x32.
