  • Patent number: 8099587
    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.

  • Publication number: 20110314431
    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.

  • Patent number: 8069048
    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.

  • Patent number: 7974840
    Abstract: A method of and an apparatus for encoding/decoding an MPEG-4 bit sliced arithmetic coding (BSAC) audio bitstream having ancillary information. A time domain audio signal is converted to a frequency domain audio signal and quantized. A number of data bits is counted and a number of available bits per layer is obtained. The number of available bits per layer is modified considering the size of ancillary information. Actual audio data is encoded in units of layers and ancillary information is embedded in the encoded bitstream. A header is decoded and a layer structure of an audio bitstream is calculated to determine the size of the ancillary information as a difference between a size of data up to a top layer and a size of a frame. The ancillary information is extracted to improve meta data and sound quality of audio contents.

  • Patent number: 7752041
    Abstract: A method and an apparatus for encoding/decoding a digital signal are provided. First, a digital input signal is transformed into samples to remove redundant information among signals. Then, a lookup table corresponding to a characteristic of the input signal is selected among a plurality of lookup tables that indicate different numbers of bits allocated for each quantization unit depending on different characteristics of input signals, and the number of bits allocated for each quantization unit is acquired from the selected lookup table. Next, a distribution of samples within each quantization unit is divided into a predetermined number of sections, and the samples are linearly quantized using the allocated number of bits on a section-by-section basis. Thereafter, a bitstream comprised of frames is produced from the quantized samples and predetermined side information so that information about a frame length is stored in the end of frame.
