Page 1. 8086 INSTRUCTION SET. DATA TRANSFER INSTRUCTIONS. MOV – MOV Destination, Source. The MOV instruction copies a word or byte of data from a specified source to a specified destination. The destination can be a register or a memory location. The source can be a register, a memory location or an.
Aim: Understanding Intel 8086 instruction set and writing an interactive program to ask for name and display it back on screen. Background: An instruction set is a list of all the instructions, and all their variations, that a processor (or in the case of a virtual machine, an interpreter) can execute. An instruction set is a list of all

This lecture describes a subset of the 80x86 architecture and instruction set. While it's not possible to cover all the details of the 80x86 you should learn enough about the 8086 instruction set to be able to write simple routines to service interrupts and read/write data to/from I/O ports. In particular, you should be able to:.
8086 Instruction Set Opcodes. Operation Operands. Opcode. ADC see ADD. ADD opcode + $10, and xx010xxx (ModR/M byte) for $80-$83. ADD r/m8, reg8. $00. ADD r/m16, reg16. $01. ADD reg8, r/m8. $02.

Some instructions generate exactly the same machine code, so disassembler may have a problem decoding to your original code. This is especially important for Conditional Jump instructions (see "Program Flow Control" in Tutorials for more information). Instructions in alphabetical order: Instruction. Operands. Description.
