Abstract: A decoding method, medium, and device decoding an input signal, including compressed multi-channel signals as a mono or stereo signal, into 2-channel binaural signals. A full band channel level of each channel in the multi-channel system is calculated from channel level differences between the channels, and data of each channel included in the input signal is localized in directions corresponding to the channels based on the calculated full band channel levels of the channels. Accordingly, the input signal can be output as the 2-channel binaural signals by using simple operations without having to reconstruct multi-channel signals from the input signal in a quadrature mirror filter (QMF) domain.

The etch proximity correction method includes creating an etch bias value from a project area corresponding to an area blocked by a pattern region within a linear distance projected from a target position selected in a target layout to an outermost portion of the proximity region and a non-project area corresponding to an area projected into an edge linear distance from an edge of the pattern region blocked in the linear distance to the outermost portion of the proximity region and correcting the target position in the layout using the etch bias value. Since an etch bias model includes the project area and the non-project area, the accurate etch bias value may be calculated.

Abstract: Provided are a scalable wide-band speech coding/decoding apparatus, method, and medium. An input wide-band speech input signal is first divided into a low-band signal and a high-band signal. The divided low-band signal is then coded using a code excited linear prediction (CELP) method. The divided high-band signal is coded using a harmonic method. A signal representing a difference between a synthetic signal obtained from the low-band and the high band, and a signal input to the low-band and the high-band is then coded using a modified discrete cosine transform (MDCT) method. The coded signal is then multiplexed. The multiplexed signal is then output. Accordingly, high quality speech can be achieved for all layers.

Abstract: An arrangement is provided for compressing microcode ROM (“uROM”) in a processor and for efficiently accessing a compressed “uROM”. A clustering-based approach may be used to effectively compress a uROM. The approach groups similar columns of microcode into different clusters and identifies unique patterns within each cluster. Only unique patterns identified in each cluster are stored in a pattern storage. Indices, which help map an address of a microcode word (“uOP”) to be fetched from a uROM to unique patterns required for the uOP, may be stored in an index storage. Typically it takes a longer time to fetch a uOP from a compressed uROM than from an uncompressed uROM. The compressed uROM may be so designed that the process of fetching a uOP (or uOPs) from a compressed uROM may be fully-pipelined to reduce the access latency.

Abstract: Provided is an etch proximity correction method in which an accurate etch bias value is calculated. The etch proximity correction method includes creating an etch bias value from a project area corresponding to an area blocked by a pattern region within a linear distance projected from a target position selected in a target layout to an outermost portion of the proximity region and a non-project area corresponding to an area projected into an edge linear distance from an edge of the pattern region blocked in the linear distance to the outermost portion of the proximity region and correcting the target position in the layout using the etch bias value. Since an etch bias model includes the project area and the non-project area, the accurate etch bias value may be calculated.

Abstract: Provided is a scalable encoding method, apparatus, and medium. The method includes: encoding a base layer and encoding a first enhancement layer and a second enhancement layer in a frame having the base layer; and generating an encoded frame by synthesizing the encoded results. Accordingly, only if the loss of the encoding frame is not as great as the encoded first enhancement layer is damaged, a case where speech restoration with respect to partial frequency bands must be given up does not occur. Furthermore, since an encoder divides the second enhancement layer into a plurality of layers in a horizontal or vertical direction, considering a distribution pattern of data belonging to the second enhancement layer and first encodes a layer in which lots of data are distributed among the divided layers, loss of audio information can be minimized even if a portion of the encoded second enhancement layer is damaged.
