In register addressing the instruction will specify the name of the register which holds the data to be operated by the instruction.Immediate Addressing
In immediate addressing mode an 8-bit or 16-bit data is specified as part of the instruction.
*8086 Memory Addressing Modes memory. This may The 8086 provides 17 different ways to access seem like quite a bit at first, but fortunately most of the address modes are simple variants of one another so they’re very easy to learn. The key to good assembly language programming is the proper use of memory addressing modes.
*The addressing mode in which the data operand is a part of the instruction itself is known as immediate addressing mode. Register indirect addressing This addressing mode allows data to be addressed at any memory location through an offset address held in any of the following registers: BP, BX, DI & SI.
There are seven addressing modes in 8086 processor. Now, we will discuss all of them in detail with example assembly instructions.Direct Addressing
In direct addressing an unsigned 16-bit displacement of signed 8-bit displacement will be specified in the instruction.The displacement is the effective address(EA) or offset.The 20 bit physical address of memory is calculated by multiplying the content of DS register by 10H and adding to effective address.In case of 8-bit displacement, the effective address is obtained by sign extending the 8-bit displacement to 16-bit.
The segment base address (BA) is computed by multiplying the content of DS by 16(base 10)The memory address (MA) is computed by adding the effective address (EA) to the segment base address (BA)Register Indirect Addressing
In register indirect adddressing the name of the register which holds the effective address(EA)will be specified in the instructionThis addressing mode allows data to be addressed at any memory location through an offset address held in any of the following registers: BP, BX, DI & SI.
This instruction moves a word from the address pointed by BX and BX + 1 in data segment into CL and CH respectively.Based Addressing Mode
In this addressing mode, the offset address of the operand is given by the sum of contents of the BX/BP registers and 8-bit/16-bit displacement.Indexed Addressing Mode
In this addressing mode, the operands offset address is found by adding the contents of SI or DI register and 8-bit/16-bit displacements.See Some Programs

In this section we will see the addressing modes of Intel 8086 microprocessor.
There are eight addressing modes in 8086 MPU. These modes are:
*
Immediate Addressing Mode
*
Register Addressing Mode
*
Direct Addressing Mode
*
Register Indirect Addressing Mode
*
Based Addressing Mode
*
Indexed Addressing Mode

Based-Index with displacement addressing modeImmediate Addressing
The addressing mode in which the data operand is a part of the instruction itself is known as immediate addressing mode.Register Addressing
It means that the register is the source of an operand for an instruction.Direct Addressing
The addressing mode in which the effective address of the memory location is written directly in the instruction.Addressing Modes Of 8086 MicroprocessorRegister Indirect Addressing
This addressing mode allows data to be addressed at any memory location through an offset address held in any of the following registers: BP, BX, DI & SI.Based Addressing
In this addressing mode, the offset address of the operand is given by the sum of contents of the BX/BP registers and 8-bit/16-bit displacement.Indexed Addressing
In this addressing mode, the operands offset address is found by adding the contents of SI or DI register and 8-bit/16-bit displacements. Mac amnesia a machine for pigs.Based Index Addressing
In this addressing mode, the offset address of the operand is computed by summing the base register to the contents of an Index register.Based Index with Displacement Addressing
In this addressing mode, the operands offset is computed by adding the base register contents. An Index registers contents and 8 or 16-bit displacement.Addressing Modes Of 8086 Microprocessor With Examples
