NOR Instruction

NOR Operation on Bits
first operand	0	0	1	1
second operand	0	1	0	1
	__	__	__	__
result	1	0	0	0

 

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 <-- bitwise NOR 
              # between $s with $t.
