Small x86/ARM Operating System built from scratch

Context Switching involves storing the context or state of a process so that it can be reloaded when required and execution can be resumed from the same point as earlier. Act of switching from one process to another is called a "Context Switch".Typically there are several tasks to perform in a computer system. So if one task requires some I/O op…

A 64-bit cooperative multi-tasking toy operating system in C

Topologic Python Library. A library to simulate DFAs and Probabilistic DFAs using context switching. This library provides a way to build and define the behavior of a graph. The client is able to define the function each vertex and edge of the graph make and how the graph transitions from one (the first valid edge) or to many states, as well as …

An Extension of Piccolo_OS_v1.1 with multi-core support and more. A simple RTOS.

Coroutines for generator functions, sequential pipelines, state machines, and other uses in C

Library for switching user-space stacks

Modifying the Linux kernel (v6.1.6) to add a system call for track context switches and a kernel module to generate signals to any process

Operating System kernel implemented with scheduling of process, memory management, kernel-threads, buddy-allocator and pipes - Subject: Operating Systems at @ ITBA

Assembly level threads implementation (thread switching demonstrated)

Multiprogramming is a process or method of executing multiple processes simultaneously in the memory. Its primary aim is to minimize the average waiting time, average turnaround time and maximize the CPU utilization. There are various CPU scheduling algorithms are used to performed multiprogramming like First Come First Serve (FCFS), Shortest Jo…

ARM Cortex-M0 Operating System

Context switching is the process of saving and restoring CPU state to switch between processes or threads for multitasking and efficient CPU time allocation. It involves storing the current process's state in the PCB and loading the state of the next process for seamless execution.
