Abstract(in English) | This paper illustrates a study to achieve a useful computer system that can recover the running state with no battery unit between unpredictable power failures of unstable power supply . This study assumes the usage of fast non-volatile memories as the system's main memory for decreasing overhead and takes an approach to store and recover the consistent state of system components consisting of the CPU, main memory and peripheral devices. First, the requirements to store and recover the system consistent state are illustrated based on the analogy of consistency of distributed (message-passing) systems. The methods to satisfy the requirements with the modification of the device driver and operating system are described. Evaluations with practical applications showed that the software-based methods have at most 0.2% or 0.5% overhead and store of running state can be done with low overhead. Additionally, a hardware support to reduce overhead still more, which is our work in progress, is illustrated. |
