Cara Menampilkan Karakter dengan Bahasa Assembly Menggunakan EMU8086

Summary

In this video, Teguh Waluyo, a student from the Faculty of Computer Science at Universitas Amikom Purwokerto, explains an assignment on assembly language. He demonstrates how to print characters using the 286 emulator, showing key commands such as 'move' and 'jump'. The tutorial covers character printing, jumping between code lines, and executing various commands like 'move dl' to display specific characters. Throughout the demonstration, he also emphasizes the flow of execution and how different commands interact. The video concludes with a practical example of using assembly language to print text like 'I am microsd' and 'Indonesia'.

Q & A

What is the primary purpose of the video?

The primary purpose of the video is to explain the use of assembly language in the emu8086 emulator, particularly for printing characters and demonstrating basic commands like `move` and `jmp`.

What software is being used for the demonstration in the video?

The software used in the video is emu8086, an emulator for running 16-bit assembly language programs.

What does the `move` instruction do in assembly language?

The `move` instruction is used to transfer data from one location to another. In this context, it's used to move a character's ASCII value into a register, such as `dl`, for printing.

How is the character 'a' printed in the video?

The character 'a' is printed by first loading its ASCII value into the `dl` register using the `move` instruction, and then using a print instruction to display it on the screen.

What is the role of the `dl` register in the demonstration?

The `dl` register is used to store the ASCII value of the character to be printed. In the video, it's loaded with the value for 'a', which is then printed.

What does the `jmp` instruction do in assembly language?

The `jmp` instruction is used for an unconditional jump in the program, causing the flow of execution to jump to a specified part of the code. In the video, it's used to jump to different locations in the program for repetitive actions.

What happens when the `jmp` command is used in the video?

When the `jmp` command is used in the video, the program flow jumps to another part of the code, skipping over sections, which allows for repeated printing or execution of different instructions.

Can you describe the sequence of commands used for printing multiple characters?

The sequence of commands for printing multiple characters involves using the `move` instruction to load the ASCII value of the character into the `dl` register, followed by a print instruction to display the character. A `jmp` command is used to loop back and print additional characters.

Why does the program loop when using the `jmp` instruction in the video?

The program loops because the `jmp` instruction causes the execution to jump back to the section of the code that contains the printing commands, allowing the characters to be printed repeatedly until the program is stopped.

What is the significance of the `move` and `jmp` instructions in assembly language?

The `move` instruction is crucial for transferring data to registers, while the `jmp` instruction allows for controlling the flow of execution, making it possible to create loops and conditional jumps in a program.
