A framework improving availability for consumer electronics

To face the challenges resulting from increasing complexity of portable consumer electronics, a dependability framework to improve the availability of application software in runtime is needed. In this paper, a system layer division based on the user event processing is given and faults are classified based on it. A hardware software co-designed application aware framework architecture proposed to handle these types of faults. And the software components on different layer are provided with separate service to improve the availability. A validation based on software-implemented fault injection is also given to evaluate the performance. And the experiment results show that the framework can achieve high coverage and fast error recovery.
