What are the APPROACHES IN THE DEVELOPMENT OF Embedded OS?

Development Approaches Advantage Disadvantage Adapting an existing commercial OS The Embedded OS derived from a commercial general-purpose OS is based on a set of familiar interfaces. The OS is not optimized for real-time and embedded applications. Purpose-Built Embedded OS (Ecos and Tiny Os) Purposely designed for tasks requiring predictable operation over fast operations, necessitating different design decisions, particularly in the area of task scheduling. Must be designed from the ground up for embedded applications
