Abstract: A device and a method for managing a file system are provided to prevent performance degradation of the file system for sectors, which are not synchronized and are not continuous by unpredictable sudden power-off, by storing a log reflecting change of metadata in a non-volatile memory storage medium. A memory(120) stores data and first metadata for the data, and a non-volatile storage medium(130) stores second metadata changed according to change of the data when the data is changed. A controller(140) updates the first metadata by using the second metadata. The controller checks remaining capacity of the non-volatile storage medium and stores the second metadata to a storage medium(110) when the remaining capacity of the non-volatile storage medium is smaller than a reference level.

Abstract: An apparatus and a method for displaying a graphic object with low power is provided to minimize the power consumption by adjusting the complexity of a displayed graphic object in consideration of the power residue of a power supply unit and increasing the light source transmittance of an LCD unit. A graphic management part(250) in an apparatus for displaying a graphic object with low power consists of a model transformation part(251), an operation load management part(252), and a pixel information transformation part(253). The model transformation part(251) transforms the polygon model of a graphic object. The operation volume management part(252) adjusts the frequency of calculation for the vertex coordinates and color tone of the polygon model. The pixel information transformation part(253) transforms the resolution of pixel information, applied to a specific area of the graphic object, based on a previously created pixel information map.
