Embedded And Real Time Systems By Kvkk Prasad Pdf



What are Embedded and Real Time Systems?




Embedded and real time systems are two types of computer systems that have specific characteristics and applications. Let's see what they are.


Definition and Characteristics of Embedded Systems




An embedded system is a computer system that is designed to perform one or a few dedicated functions within a larger system. It is usually embedded as a part of a complete device that includes hardware and mechanical parts. An embedded system has the following characteristics:


  • It has limited resources such as memory, processing power, battery life, etc.



  • It has strict constraints on performance, reliability, safety, security, etc.



  • It has a predefined specification and functionality that cannot be changed easily.



  • It interacts with the physical world through sensors and actuators.



  • It operates in real time or near real time.



Definition and Characteristics of Real Time Systems




A real time system is a computer system that is required to respond to events or inputs within a specified time limit. The correctness of a real time system depends not only on the logical results of the computation, but also on the time at which the results are produced. A real time system has the following characteristics:


  • It has deadlines or timing constraints that must be met.



  • It has unpredictable or dynamic workloads that vary depending on the inputs or events.



  • It has high availability and dependability requirements.



  • It has concurrent processes or tasks that need to be synchronized and coordinated.



  • It has complex algorithms or logic that need to be optimized for efficiency.



Examples and Applications of Embedded and Real Time Systems




Embedded and real time systems are widely used in various domains such as aerospace, automotive, industrial automation, medical devices, telecommunications, consumer electronics, etc. Some examples of embedded and real time systems are:
