NOR Instruction

NOR Operation on Bits
first operand 0011
second operand 0101
 
result 1000

There is a bitwise NOR instruction. There is no immediate operand NOR instruction. NOR is equivalent to performing the OR operation, then complementing the bits (change 0 to 1 and 1 to 0). Here is the assembly language for it:

nor  d,s,t    # $d gets bitwise NOR 
              # between $s with $t.

QUESTION 10:

What is the bitwise NOR of the following?
