The present invention relates to a low density parity check (LDPC) encoding method and an apparatus thereof. In the LDPC encoding method, a matrix multiplication corresponding to ET⁻¹ and T⁻¹ is eliminated according to a structural characteristic in an encoding process. Accordingly, shift weights that are not −1 among shift weights corresponding to partial blocks A, B, and C of a parity check matrix are used to perform an encoding operation, and a cyclic shift operation of an information unit block is performed in parallel so that a first parity block and a second parity block may be simultaneously generated.

Described are techniques for managing a sequential stream in a data storage system. A front-end component receives a plurality of data operations for a plurality of data portions and determines that the plurality of data portions are associated with a sequential stream. Each of the plurality of data portions of the sequential stream is associated with a sequential stream identifier, and a position indicator uniquely identifying a position of said each data portion in said sequential stream. Each of the plurality of data portions that is prefetched is associated with a remaining prefetched identifier and included in a prefetched chunk of data portions. The front-end component uses information about said sequential stream in connection with managing said sequential stream. The information includes the sequential stream identifier, one or more position indicators, and one or more remaining prefetched identifiers.

A non-volatile memory system mitigates the effects of open block reading by analyzing the un-programmed region of a block before programming to determine a potential for read disturbance. The system may determine a read count value associated with open block reading of the memory block and/or perform partial block erase verification. To mitigate the effects of open block read disturbance, the system performs partial block erase for the un-programmed region of the memory block and/or limits programming in the un-programmed region.

To provide a display device capable of displaying a moving picture with high definition and at high speed. An image display system includes: an image display unit; and a control unit. The control unit has: a block discrimination circuit portion; an image processing portion; a storage portion; and a synchronizing signal generation portion. The block discrimination circuit portion discriminates a moving picture or a still picture to process the image information in accordance with the discriminated result, in which the number of gradations for the image information processed when the discriminated result is the moving picture is lower than when the discriminated result is the still picture. Thereby, the high definition image display and the high speed moving picture display can be effected by reducing the information with lower degree of recognition.

A system and associated method load an input data stream into a multi-dimensional clustering (MDC) table or other structure containing data clustered along one or more dimensions, by assembling blocks of data in a partial block cache in which each partial block is associated with a distinct logical cell. A minimum threshold number of partial blocks may be maintained. Partial blocks may be spilled from the partial block cache to make room for new logical cells. Last partial pages of spilled partial blocks may be stored in a partial page cache to limit I/O if the cell associated with a spilled block is encountered later in the input data stream. Buffers may be reassigned from the partial block cache to the partial page cache if the latter is filled. Parallelism may be employed for efficiency during sorting of input data subsets and during storage of blocks to secondary storage.
