Abstract:
PURPOSE: A storage device and a driving method are provided to rapidly rearrange the data in a storage area corresponding to the amount of data shared, thereby easily managing the data. CONSTITUTION: A data storage unit(10) includes a first storage area and a second storage area corresponding to a different physical address and stores the first data in the first storage area. A first memory(21) stores the amount of first data shared. When the amount of the shared first data is changed, a controller(30) rearranges the first data from the first storage area to a second storage area. The first storage area stores the data to which the shared amount is included in the first range. The second storage area stores the data to which the shared amount is included in the second range.
Abstract:
An image sensor according to an embodiment of the present invention comprises: a pixel array including a plurality of sub-pixel groups, each of which includes a plurality of sub-pixels for generating a sub-pixel signal corresponding to one photocharge accumulated in response to a photon; and a low drive block for generating a first control signal to control action of the pixel array, wherein the first control signal controls the plurality of sub-pixels included in the same sub-pixel group to accumulate the photocharge from a first time point to a second time point. Therefore, according to the image sensor of the embodiment of the present invention, an image distortion caused by a time difference in photocharge accumulation can be eliminated by enabling sub-pixels in a sub-pixel group having a binary output to accumulate photocharge at the same time.
Abstract:
PURPOSE: A data deduplication system and a method thereof are provided not to maintain an unnecessarily huge index table, thereby using efficiently a storage space. CONSTITUTION: A pre-processor (110) receives data files and determines each type of the data files. A chunking module (120) chunks the data files to produce chunks. A hash engine (130) generates the hash value of the chunks. A fingerprint detector (140) determines whether the hash value of the chunks exists in an index table (150) corresponding to each type of the data file. According to each type of the data file, the chunking module selects a first or second method and chunks the data file. The first method includes content defined chunking (CDC), and the second method includes static chunking (SC).
