Question 19

+3 marksWritten answer

Suppose we want to execute a data movement instruction, where we move the data present in register R3R_3 to register R21R_{21}.

Instruction: MOV Rd,RrR_d, R_r

RdR_d: Destination register, RrR_r: Source register

Operands: 0≤d≤31,0≤r≤310 \le d \le 31, 0 \le r \le 31

Instruction Format:

001011rddrdrrrdd

What will be the hexadecimal machine code for the instruction?

Note: Enter the value in hexadecimal format (e.g., 0x2438).

Show answer

Correct answer: 0x2D4D
