Frameworks for embedded system development

Embedded systems with moderate or high complexity are increasingly emerging in our environment Developing software for such systems could be done from scratch or by using existing system or framework Building from scratch is very time and cost demanding. Using existing operating system for embedded systems as base may not be always good choice due to cost, licensing, complexity or inflexibility. In this paper we propose using various frameworks which consists of only particular operating system kernel components for embedded system development of various complexities.
