Title: Design and Implementation of a Virtual Computer Simulator
Abstract:
This paper presents the design and implementation of a virtual computer simulator program in the C programming language. The purpose of this simulator is to accept pseudo code input, compile it into an array, and execute the code based on the integers in the array. The simulator aims to provide a realistic emulation of a computer system, capturing the essential features of a modern computer architecture. This paper will discuss the overall design approach, the data structures used, as well as the implementation details of the key functionalities.
1. Introduction
1.1 Background
In the field of computer science, simulator programs play a crucial role in understanding and exploring the behavior of complex systems. A virtual computer simulator provides a means to simulate the execution of computer programs without accessing real hardware. Such simulators are particularly useful in the development and testing of applications, as well as in educational settings for teaching computer architecture and programming concepts.
1.2 Objectives
The main objective of this project is to develop a virtual computer simulator that can execute pseudo code provided by the user. This simulator will compile the pseudo code into an array representation and execute it based on the integers in the array. The simulator will have the capability to emulate typical operations performed by a computer, including memory management, arithmetic calculations, and control flow. The primary aim is to provide an accurate emulation of a basic computer system, allowing users to interact with the simulation and observe the execution of the code step by step.
2. Design and Architecture
2.1 Overall Structure
The virtual computer simulator is designed in a modular fashion, comprising several independent components that interact to perform the simulation. The main components include the compiler, memory manager, arithmetic unit, control unit, and input/output handlers. The program follows a top-down design approach, with each component encapsulating its functionality and providing the necessary interfaces for communication with other components.
2.2 Data Structures
To represent the compiled code, an array-based data structure is employed. The array is capable of storing integers that correspond to specific operations or instructions. Additionally, separate data structures are utilized to manage memory allocation, register values, and control flow information. These data structures allow for efficient storage and retrieval of information during the simulation.
3. Implementation Details
3.1 Compiler
The compiler component is responsible for parsing the pseudo code and translating it into the corresponding array representation. This process involves splitting the code into individual tokens, analyzing the syntax and semantics, and mapping each token to its respective integer representation. The compiler ensures that the generated array meets the requirements of the simulator’s execution model.
