Implementation of Dynamic Semantic Evolution of Embedded Systems

Embedded systems which are used for monitoring and controlling safety and mission critical systems cannot be shut down for want of making changes to the ES software for the reasons of updating, adding and deleting tasks. ES software must evolve dynamically while the software is up and running due to the criticality reasons. Many architectures have been presented related to loaded systems and few related to embedded systems for effecting semantic evolution of the embedded software. Dynamic evolution of embedded software is quite complicated due to the availability of fewer resources and especially when the evolution has to be carried under the influence of a real time operating system (RTOS). In this paper the implementation of dynamic semantic evolution of embedded software which runs under an RTOS has been presented.
