The rapid growth of applications deploying real-time technologies has been matched by the evolutionary growth of the underlying technologies supporting the development of real-time systems. In this course, some of the core technologies used in developing real-time systems will be discussed. Mainly, the software issues related to real-time systems will be discussed, keeping the hardware discussions to bare minimum. The software issues that will be addressed are quite expansive, including the operating system and program development issues, the networking and database issues, etc. Also, some of the popular commercial real-time operating systems and their important features will be discussed in this course.

Intended audience: CSE, IT

Prerequisites: Operating Systems
