REAL TIME OPERATING
SYSTEM
What is Real Time ?
• “ Real time in operating systems:
The ability of the operating system to provide a
required level of service in a bounded response
time.”
• It responds to inputs immediately(Real-Time).
What is Real Time ?
• Here the task is completed within a specified time
delay.
• In real life situations like controlling traffic signal or
a nuclear reactor or an aircraft,
• The operating system has to respond quickly.
WHAT IS RTOS.
Hard RTOS…
• A hard real-time system has time-critical deadlines that must
be met; otherwise a catastrophic system failure can occur.
• Absolutely, positively, first time every time
• Requires formal verification/guarantees of being to always
meet its hard deadlines (except for fatal errors).
• Examples:
– air traffic control
– vehicle subsystems control
– Nuclear power plant control
Hard RTOS…
Soft RTOS…
• In a soft real-time system, it is considered undesirable, but not
catastrophic, if deadlines are occasionally missed.
• Also known as “best effort” systems
• Most modern operating systems can serve as the base for a
soft real time systems.
• Examples:
– multimedia transmission and reception,
– networking, telecom (cellular) networks,
– web sites and services
– computer games.
CONCLUSION.
RTOS have been the heroes in most of the technological
areas, right from fuel injection system to nuclear reactor
control, satellite control, global positioning systems, and
fully equipped high-tech warfare aircrafts. And the best is
yet to come!
THANK YOU
