This project involved the development of a x86 64 bit operating system (SBUnix). It was developed in C and Assembly language. System was tested on QEMU which is a hosted hypervisor that performs hardware virtualization.The developed OS support for Context Switching, Memory management, File System, Terminal and Shell. System calls: COW fork, execvpe, sleep, malloc, exit,read, write, wait, waitpid,ls, ps, scanf etc. Memory management : 4 level Paging , virtual memory management in Ring 0 and Ring 3, Page-fault Handling etc. File-System : PCI bus and AHCI sata device controller interfacing and management, system calls (fread,fwrite, fseek, opendir, readir, mkdir) This project was undertaken as a part of CSE 506 Operating Systems course.

SBUnix is x86 64 bit operating system majorly developed in C. It supports memory management, paging, context switching, terminal, shell and file management for tarfs and disk.

CSE 506: A custom OS kernel built from scratch. Features multi-level paging, preemptive scheduling, multitasking, TAR file system support, and an interactive shell. Ideal for understanding the intricacies of OS design and kernel development. A practical, hands-on approach for learners and system programmers. 🖥️👨‍💻🛠️

A 64 bit Unix OS SBUnix developed at SBU

A pre-emptive multi-tasking kernel using FreeBSD boot-loader for x86-64 architecture.

SBUnix Operating System - A x86-64 bit operating system for Intel x86 processor

OS written as part of course at Stony Brook University - Spring 2015

Creating a non-trivial 64-bit operating system that boots on and manages real hardware. Implementing functionalities like a shell, standard libraries, Interrupt handling, an AHCI and Memory, Process, I/O, etc.

64-bit Operating system developed as a part of the CSE-506 (Operating Systems) course under Prof. Mike Ferdman

A simple Preemptive Operating System. It contains implementation of various kernel level components like Virtual Memory sub system, Process sub System, User level sub system. It includes Context switching, Copy on write fork, execve, auto-growing stack, Interrupt handling and so on. Also, there is support to run a user level shell. The shell functionalities are – changing the current directory, executing scripts, pipelines of binaries, PATH and PS1 variables etc.
