Real-time systems play a considerable role in our society, and they cover a spectrum from the very simple to the very complex. Examples of current real-time systems include the control of domestic appliances like washing machines and televisions, the control of automobile engines, telecommunication switching systems, military command and control systems, industrial process control, flight control systems, and space shuttle and aircraft avionics.

All of these involve gathering data from the environment, processing of gathered data ....etc

Operating System Structure
A key concept of operating systems is multiprogramming.
Goal of multiprogramming is to efficiently utilize all of the computing resources.
When a job issues an I/O request (e.g., open a file, read data from a file), it cannot continue until the request is fulfilled.
The CPU then becomes idle (the job is blocked on the request).
Operating System Structure
Basic idea of multiprogramming:
Keep multiple jobs in memory.
When one ....etc

A real time system is defined as follows - A real-time system is one in which the correctness of the computations not only depends upon the logical correctness of the computation but also upon the time at which the result is produced. If the timing constraints of the system are not met, system failure is said to be occurred.


Two types Hard real time operating system Strict time constraints Secondary storage limited or absent Conflicts with the time sharing systems Not supported by general purpose OS Soft real time operating system Reduc ....etc

RTX51 Real-time Operating System

RTX51 Full is a full-blown real-time kernel. It supports
up to 256 tasks and provides control over semaphores,
task signals, message queues, and memory pools. It is
designed for 8051-based applications that have numerous
tasks and many resources to manage. CAN support is
provided for a number of 8051-based CAN
microcontrollers as well as many external CAN
controllers.
RTX51 Tiny is a small real-time kernel (around 800
bytes). It supports applications that have reduced
real-time requirements. ....etc
