Arithmetic and Logic Instructions in Microprocessor 8086/8088

Any ADD instruction modifies the contents of the sign zero carry auxiliary carry parity and overflow flags Example: ADD AX BX ADD AX CX ADDAX DX; adds BX to AX register; adds CX to AX register; adds DX to AX register Arithmetic Instructions ADD: Addition

What is the difference between 8085 and 8086 microprocessor?
Unlike in 8085 microprocessor, in 8086 microprocessor the destination operand need not be the accumulator. Following is the table showing the list of arithmetic instructions: Here D stands for destination and S stands for source. D and S can either be register, data or memory address.
What is loop in 8086?
In 8086 LOOP decrements CX. This instruction is used to repeat a group of instructions some number of times, or until the zero flag becomes 0. The number of times the instruction sequence is to be repeated is loaded into CX. Each time the LOOP instruction executes, CX is automatically decremented by 1.
What are addition instructions in 8086 microprocessor?
8086 microprocessor supports following types of addition instructions. Now lets discuss the details of Addition instructions with assembly code examples. This instruction adds the data of destination and source operand and stores the result in destination.
Does the 8086 CPU support indirect mode?
No, they don't do the same thing. The 8086 CPU supports an indirect mode, where a register is treated as holding an address of a value rather than the value itself. The brackets surrounding the register, as in [BX], were used by the assembler to signal that the assembler was to produce one of these addressing modes.
