Study Notes
Addressing Modes in 8086
- Register Addressing mode specifies the source and destination operand, often contained in the registers of 8086.
- Addressing modes in 8086 can be broadly classified into two groups: Immediate and Memory.
Instruction Set
- The 8086 instruction set contains three types of instructions: Data Transfer, Arithmetic, and Control.
Purpose of Addressing Modes
- The purpose of addressing modes in 8086 is to specify the source and destination operands for an instruction.
Instruction Set Size
- There are 8086 instructions in the 8086 instruction set.
Data Flow Direction
- The data flow direction is from the source to the destination.
Registers
- Data is copied from the BX register in the given context.
Immediate Addressing Mode
- Immediate Addressing mode allows 8 or 16-bit data to be specified as part of the instruction.
Direct Addressing Mode
- In Direct Addressing mode, the effective address is specified directly in the displacement field of the instruction.
MOV Instruction
- The instruction 'MOV [DI], BX' copies the contents of the BX register to the memory location specified by the DI register.
