Queue Implementation in x86_64 Assembly Language with C interface

by Jerry McIntosh

---

INTRODUCTION

This is an Assembly Language implementation of a Queue (FIFO). The Queue is implemented as a shared-library with a C interface. There is also a C demo program.

LIST OF REQUIREMENTS:

• Linux OS
• Programming languages: C and Assembly
• Netwide Assembler (NASM), the GCC compiler, and the make utility
• your favorite text editor
• and working at the command line

---

CREATE THE DEMO

Run the following command in the Queue-main folder:

sh ./queue_make.sh

---

RUN QUEUE DEMO

In the qtest folder enter the following command:

./go_qtest.sh

---

THINGS TO KNOW

You can modify a couple defines in the C header file main.h:

#define DATA_COUNT    28

Modifying these defines will change the behavior of the demo program.

There are calls to printf in the queue.asm file. They are for demo purposes only and can be removed or commented out. The printf code sections are marked with comment lines: BEGIN PRINTF; and END PRINTF. The format and text strings passed to printf are in the .data section of the queue.asm file.

Have Fun!
