隐式寻址模式和立即寻址模式之间的区别

先决条件–寻址模式
1.隐式寻址模式：
在隐含寻址模式下，操作数在指令定义中隐式指定。所有引用使用累加器的寄存器的指令均为隐含模式指令。在堆栈组织的计算机中的零地址指令也为隐含模式指令。也称为堆栈寻址模式。

2.立即寻址模式：
在立即寻址模式下，操作数是在指令本身中指定的。在此模式下，操作数字段包含要与指令中指定的操作结合使用的实际操作数。

隐式寻址模式和立即寻址模式之间的区别：

S.No.	Implied Addressing Mode	Immediate Addressing Mode
1.	In Implied addressing mode, no operand is specified in the instruction .	In Immediate addressing mode, operand is specified in the instruction itself .
2.	Basically, the operands are specified implicitly in the definition of instruction .	Here, the operands are contained in an operand field rather than address field .
3.	This type of mode can be used in all register reference instructions .	This type of mode is quite useful for initializing the registers to a constant value .
4.	It requires 8 bits or 16 bits long data and is the part of instruction.	It requires more bits than the address.
5.	There is no need to acquire a operand .	It is fast in acquiring an operand .
6.	Zero-address instructions in a stack-organized computer are implied-mode instructions .	The address field of an instruction may specify either a memory word or a processor register.
7.	Example: CMA (Complement Accumulator)	Example: MVI A 45
