Data manipulation instructions perform operations on data and provide computational capabilities for computers. These instructions are divided into three basic types: arithmetic instructions, logical and bit manipulation instructions, and shift instructions. Arithmetic instructions include addition, subtraction, multiplication, division, and incrementing and decrementing values. Logical and bit manipulation instructions operate on individual bits and include AND, OR, XOR, and clearing, complementing, and manipulating carry bits. Shift instructions shift the contents of an operand left or right in logical, arithmetic, or rotate operations.

2. Decrement (DEC):-this instruction subtracts 1 from the value stored in a register or memory word. - One common characteristic of decrement operations when executed in processor registers is that a binary number of all 0’s when decremented, produces a result of all 1’s. ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
7. Add with Carry (ADDC):- A special carry flip- flop is used to store the carry from an operation. The instruction “add with carry” performs the addition on two operands plus the value of the carry from the previous computational. ,[object Object],[object Object]
