Infotainment systems' boot time is consumed more than the car's boot time. Thus, if infotainment systems is applied boot-free computing, it can solve this disadvantage. We must use a non-volatile memory such as SCM (Storage Class Memory) to make to boot-free computing because system context must be remained on memory when device power is gone. In this architecture, the non-volatile SCM can store dynamic...
A Flash File System for Fast Recovery (FFS-FR) is proposed in this paper. It uses the links between inodes in a flash file system based on the CFFS (Core Flash File System). The FFS-FR is able to restore the consistency of the metadata quickly by reading only the inodes instead of reading the whole flash area. The experimental results show that the recovery time of the proposed technique is 450, 150,...
This paper proposes Block Link(BL) file system which provides high-speed multimedia files editing and storing technique. When editing and storing large-scale multimedia files, the BL file system does not need data I/O, needs only modification of the metadata. In addition, by sharing data blocks among multimedia files, the BL file system can save storage space. The BL file system is based on Ext3 file...
This paper proposes a novel timeout scheduling scheme for data aggregation in wireless sensor networks, which adaptively configures both the length of timeout and the collecting period according to the potential level of event occurrence. At normal times, the proposed scheme decreases the length of timeout that is a waiting time for messages from child nodes, and it makes longer the collecting period...
In this paper, an overview of a new GIS (gas insulated switchgear) PD (partial discharge) diagnostic algorithm for both single-defects and multi-defects in HiPDS-G (Hyundai intelligent preventive diagnostic system for GIS) developed by HHI(Hyundai Heavy Industries Co., Ltd) is given. The work includes PD defects data acquisition and analysis, ANN (artificial neural network) modeling as an automatic...
