Building a Parking Fee Management System: A Triumph of Computer Organization and Assembly Language
3rd Semester COAL Final Lab Project
Introduction
In the realm of computer science and engineering, the fusion of theory and practice is essential for the comprehensive understanding of fundamental concepts. One such prime example is the Computer Organization and Assembly Language course, where students delve into the intricate world of low-level programming and the inner workings of computer systems. As the culmination of this educational journey, the final lab project often stands as a testament to the student's proficiency and creativity. In this article, we explore a noteworthy exemplar of this course – the Parking Fee Management System – an assembly language marvel that demonstrates the synthesis of theoretical knowledge and practical application.
Tools Used
The System is built using a variety of technologies, including:
Assembly Language
ASM Compiler
Understanding the Concept
The Parking Fee Management System is a highly relevant and pragmatic project that simulates the management of parking lots. The project's objective is to automate the process of storing data when a vehicle enters the parking lot and calculating the parking fee when the vehicle exits. This endeavor demands the utilization of assembly language, which operates at a lower level of abstraction, providing a direct link to the computer's hardware components.
The Project Workflow
The project's workflow can be summarized into two fundamental phases: entry and exit.
Entry Phase
Vehicle Entry: When a vehicle arrives at the parking lot, the system captures essential details such as the vehicle's license plate number, entry time, and type of vehicle (e.g., car, motorcycle).
Data Storage: The collected information is stored in memory, creating a record of the vehicle's presence within the parking premises. This record forms the basis for fee calculation during the exit phase.
Exit Phase
Vehicle Exit: Upon the vehicle's departure, the system records the exit time and calculates the duration of the stay.
Fee Calculation: The duration of stay is then used to compute the parking fee, considering factors such as the type of vehicle and the parking rate. These calculations are often based on predefined rules, with different rates for varying vehicle types and extended stays.
Fee Generation: Once the parking fee is calculated, the system generates a fee receipt for the vehicle owner, displaying crucial information including the license plate number, entry and exit times, calculated fee, and any additional charges.
Key Components and Concepts
Data Storage: Assembly language programming involves handling data at a low level, requiring meticulous memory management. The Parking Fee Management System must allocate memory for each vehicle's entry and exit information, utilizing appropriate data structures and memory manipulation instructions.
Time Calculation: Precise time calculation is vital for determining the duration of a vehicle's stay. Assembly language facilitates interfacing with the system's internal clock to capture accurate timestamps.
Conditional Logic: Efficient use of conditional statements is pivotal for calculating parking fees based on various parameters such as vehicle type, duration of stay, and special discounts.
Output Generation: The generation of clear and informative output is paramount. The assembly language program must format and display the fee receipt with accuracy and user-friendliness.
Learning Outcomes
The development of a Parking Fee Management System as a final lab project yields an array of invaluable learning outcomes for students:
Assembly Language Proficiency: Students gain hands-on experience in assembly language programming, honing their skills in manipulating registers, memory, and performing intricate calculations.
Memory Management: Understanding memory allocation and manipulation is essential in assembly language. This project reinforces this understanding by necessitating efficient data storage and retrieval mechanisms.
Algorithmic Thinking: Crafting algorithms to calculate parking fees and process data showcases students' prowess in algorithmic thinking and problem-solving.
Real-world Application: By simulating a practical scenario, students grasp the real-world relevance of the theoretical concepts studied throughout the course.
Project Management: Completing a comprehensive project involves planning, time management, and debugging. These skills are nurtured as students tackle challenges in creating a functional system.
Conclusion:
The Parking Fee Management System stands as a testament to the synergy between theoretical knowledge and hands-on application. Through the intricate use of assembly language, students are empowered to translate abstract concepts into functional systems with real-world applications. This project not only exemplifies the depth of understanding attained through the Computer Organization and Assembly Language course but also signifies the potential of computer science education to bridge theory and practice, equipping future engineers with the skills to innovate and create in the digital age.
