This document discusses real-time operating systems (RTOS). An RTOS is a data processing system that can process inputs and respond within a small time interval. It ensures tasks are completed within a specified time delay by responding quickly to inputs. RTOS enable multitasking and prioritized process threads. They see widespread use in modern telecommunications, military operations, radar systems, and more. RTOS are either hard real-time systems that guarantee critical tasks finish on time with no virtual memory, or soft real-time systems that prioritize critical tasks over others but are less restrictive and not catastrophic if deadlines are missed.

Real time operating system
- 2. What is Real-Time OS? • Data processing system • Time interval to process and respond to input is small • Time taken by system to respond to the input and display the output is “Response time” • Task is completed within a specified time delay • Response quickly to inputs
- 3. Application of Real-time OS • Modern telecommunication systems • Radar systems, network switching control, satellite monitoring, GPS, satellite launching • Increasingly being used in strategic and military operations • Track and trace spy satellites
- 4. RTOS require: • Multitasking • Process threads that can be prioritized • A sufficient number of interrupt levels VxWorks 6.0 created by Wind river is one of the popular Real-time OS
- 5. Types of Real-time OS Hard Real-time system • Guarantee that critical task complete on time • Secondary storage is missing • Data is stored in ROM • No virtual memory • Catastrophic • Used in air traffic control, nuclear power plant control Soft Real-time system • Less restrictive • Critical task gets priority over other tasks • Have limited utility • Used in multimedia, virtual reality, computer games, networking etc • Not catastrophic
