A software framework in single-chip based on message driven method

In this paper, we present a software framework in single chip machine (SCM) based on the message-driven method which used to be applied in message-driven operating system in PC. Due to the computing limitations of SCM, many crucial design patterns and components of the PC operating system, including soft-timer, User Interface, message classification and instruction queue should be redesigned to be adapted to the new environment. We illustrate our design and implementation with a real example of rotating camera platform. In particular, strictly following fine software designing principles, the framework is highly decoupled, easily extendible and fault tolerant.
