Cmp-arithmetic instruction-microprocessor, Assembly Language

Assignment Help:

CMP: Compare: - This instruction compares the source operand, which can be a register or memory location an immediate data with a destination operand that might be a register or a memory location. For the purpose of comparison, it subtracts the  source  operand  from  the destination  operand  but does  not stock up the result anywhere. The flags are affected and depending on the result of the subtraction. If both of the operands are equal to zero flag is set. If the source operand is higher than the destination operand, carry flag is set or else is reset. The instance of this instruction are following:

Example :

1. CMP      BX,         0100H          Immediate

2. CMP      0100                          Immediate [AX implicit]

3. CMP      [5000H],OIOOH          Direct

4. CMP      BX,         [SI]               Register indirect

5. CMP      BX,         CX                Register
