PDF	Help for Emu8086 Where to start? 1 Start Emu8086 by selecting its icon from the start menu or by running Emu8086 exe 2 Select \"Samples\" from \"File\" menu 3 Click [Compile and Emulate] button (or press F5 hot key) 4 Click [Single Step] button (or press F8 hot key) and watch how the code

What is HLT emulator & emu8086?
HLT Emulator does not reproduce any original I/O ports of IBM PC, instead it has virtual devices that can be accessed by IN/OUT instructions. "Emu8086" supports additional devices that can be created by 3rd party vendors. Device can be written in any language, such as: Visual Basic, VC++, Delphi.
Is emu8086 a good assembler?
Emu8086 has a much easier syntax than any of the major assemblers, but will still generate a program that can be executed on any computer that runs 8086 machine code; a great combination for beginners! Note: If you don't use Emu8086 to compile the code, you won't be able to step through your actual source code while running it. Where to start?
How do I run emu8086?
Start Emu8086 by selecting its icon from the start menu, or by running Emu8086.exe. Select "Samples" from "File" menu. Click [Compile and Emulate] button (or press F5 hot key). Click [Single Step] button (or press F8 hot key), and watch how the code is being executed.
How to copy values from source to destination in emu8086?
symbol for variables that are not initialized. As you probably know from part 2 of this tutorial, MOV instruction is used to copy values from source to destination. RET ; stops the program. Copy the above code to Emu8086 source editor, and press F5 key to compile and load it in the emulator. You should get something like:

What Is Assembly Language

Assembly language is a low-level programming language that is very fast, uses fewer resources compared to higher-level languages, and can be executed by translating directly to machine language via an assembler. According to Wikipedia: We know that a processor (also known as CPU - Central Processing Unit) executes all types of operations, effective

Assemblers and Editors

Assemblers are programs that translate assembly language code to its equivalent machine language code. There are many assemblers targeting various microprocessors in the market today like MASM, TASM, NASM, etc. For a list of different assemblers, visit this Wikipedia page. Code editors are software in which you can write the code, modify and save i

Code Structure

We can simply write the assembly code and emulate it in emu8086, and it'll run. However, without calling the exit statements or halt instruction, the program will continue executing the next instruction in memory until it is halted by OS or emu8086 itself. The assembly code is saved in a .asmfile type. There are also some good practices like defini

Registers and Flags

Registers are superfast memory directly connected to the CPU. The emu8086 can emulate all internal registers of the Intel 8086microprocessor. All of these registers are 16-bit long and grouped into several categories as follows, 1. General purpose registers: There are four general purpose registers, each divided into two subgroups, low and high. Fo

Assembly Language Instructions

A total of 116 instructions are available for the Intel 8086 microprocessor. All these instructions with related examples are provided in this link. In this article, I'll focus only on a few instructions necessary for understanding the later parts. 1. Copy data (MOV):This instruction copies a byte (8-bit) or a word (16-bit) from source to destinati

Working with Variables

In an assembly program, all variables are declared in the data segment. The emu8086 provides some define directives for declaring variables. Specifically, we'll use DB (define byte) and DW(define word) directives in this article which allocates 1 byte and 2 bytes respectively. Here, variable-nameis the identifier for each storage space. The assembl

Taking User Input

The emu8086 assembler supports user input by setting a predefined value 01 or 01H in the AH register and then calling interrupt (INT). It will take a single character from the user and save the ASCII value of that character in the ALregister. The emu8086 emulator displays all values in hexadecimal. dev.to

Displaying Output

The emu8086 supports single character output. It also allows multi-character or string output. Similar to taking input, we have to provide a predefined value in the AH register and call interrupt. The predefined value for single character output is 02 or 02H and for string output 09 or 09H. The output value must be stored in the general-purpose dat

Branching Or Using Conditions

We can simulate if-else conditions supported by higher-level programming languages using CMPand jump instructions. Some frequently used conditional jump instructions are, There is also JMP instruction that works similar to else statements found in higher-level languages. Following is an assembly code that compares AL register value to 5 and sets an
