Expert Solution
Step 1

As part of our regulation, in one question we can answer maximum 3 sub parts. So I have answered 3 parts. If you want answer for other two then you will have to repost the question asking for other 2.

 

1. NEG :- It takes one operand as input and returns its 2's complement form.

    NOT :- It also takes one operand as input and returns its 1's complement form.

2. DIV :- It takes two operands(unsigned numbers) as input and is used to divide unsigned numbers.

    IDIV :- It also takes two operands(signed numbers) as input and is used to divide signed numbers.
