A memory device is provided as follows. A memory cell region includes a plurality of blocks, each block including a plurality of NAND strings. A control logic divides the plurality of blocks into a plurality of block regions based on a smaller distance of a first distance with respect to a first edge of the memory cell region and a second distance with respect to a second edge of the memory cell region and controls an operation performed on the memory cell region using a plurality of bias sets of operation parameters for the operation. Each bias set is associated with one of the block regions.

Provided are a method and apparatus for compensating motion of a moving image. The method includes calculating a pixel value of a pixel located between pixels of a reference image corresponding to a current image based on pixel values of the pixels of the reference image by using at least one method from among a plurality of methods, such as a vertical linear filtering, a horizontal linear filtering, and a cubic filtering, of interpolating the pixels of the reference image according to codec information indicating one of a plurality of codecs, such as MPEG4, H.264/AVC, and VC1, and restoring the current image by adding motion compensation data, including the calculated pixel value, and a difference between the reference image and the current image.

Provided is a motion compensation method and apparatus. The motion compensation method includes performing register setting for motion compensation of an mth macroblock of a current image, performing prediction for the mth macroblock simultaneously with performing register setting for motion compensation of an (m+1)th macroblock, and performing reconstruction for the mth macroblock based on a prediction result simultaneously with performing prediction for the (m+1)th macroblock. By parallely processing motion compensation on macroblocks, the amount of time required for motion compensation of the macroblocks can be reduced.

An apparatus and method sequentially parses bitstreams based on a removal of an Emulation Prevention Byte (EPB). The apparatus and method may detect an EPB pattern from among sequentially input bitstreams, may store the bitstreams, may store a processed bitstream where the EPB pattern is removed, among the bitstreams, and may select an output of a register buffer based on an input of a buffer selection flag.

Provided is a data processing method that may transmit, from a host unit including at least one host to a tiling unit, an input parameter and first data, tile the first data using a predetermined block interleaving scheme to convert the first data to second data, and store the converted second data in a memory unit. The data processing method may transmit, from a host unit including at least one host to an inverse tiling unit, an input parameter and a request signal for first data, extract second data corresponding to the request signal from the memory unit to store at least one second data that is tiled using a predetermined block interleaving scheme, and may transmit, to the host unit, the first data that is converted by inverse tiling the second data. Here, the first data may be in a data structure of a sequential scanning scheme.

摘要:
Provided are a method and apparatus for buffering image data for motion compensation. One of two buffers of a double register array buffer, i.e., a first buffer, is selected as a buffer in which data corresponding to a row of a block of an image is to be written and the other of the double register array buffer is selected as a buffer from which data corresponding to another row of the block is to be read, thereby speeding up motion compensation processing when compared with the use of a single register array buffer.

A deblocking filtering method may includes setting first through nth macroblock groups which are adjacent to one another in a column direction and sequentially performing deblocking filtering on the first through nth macroblock groups. Each macroblock group may include at least one macroblock. An image processing device may include a deblocking filter that performs deblocking filtering in macroblock units; and a control unit that sets first through nth macroblock groups, which are adjacent to one another in a column direction, and that controls the deblocking filter to sequentially perform deblocking filtering on the first through nth macroblock groups. Once again, each macroblock group may include at least one macroblock.
