Abstract: Methods and structures are disclosed for aligning high speed data across a plurality of lanes. In one embodiment, a method and integrated circuit (“IC”) is provided for receiving and aligning scrambled training data across a plurality of data lanes before the data is descrambled. In some implementations, a known scrambled training pattern is different in each lane and alignment includes comparing incoming training data in each lane to different known scrambled training patterns in each lane. In some implementations, after scrambled data is aligned and then descrambled, it is checked against a known unscrambled training pattern to make sure that alignment of the scrambled training data was correct. In an alternative embodiment, data is descrambled before being aligned, but deskew circuitry output is monitored to determine if a training pattern ends at the same time across the plurality of lanes being aligned. If not, then data in a lane for which the training pattern ends earliest is delayed by an amount corresponding to the length of one or more cycles of the training pattern.

Abstract: Least Square Deconvolution (LSD) uses quantitative allele peak area derived from a sample containing the DNA of more than one contributor to resolve the best-fit genotype profile of each contributor. The resolution is based on finding the least square fit of the mass ratio coefficients at each locus to come closest to the quantitative allele peak data. Consistent top-ranked mass ratio combinations from each locus can be pooled to form at least one composite DNA profile at a subset of the available loci. The top-ranked DNA profiles can be used to check against the profile of a suspect or be used to search for a matching profile in a DNA database.

Abstract: An integrated circuit like a programmable logic device (“PLD”) includes multiple channels of data communication circuitry. Circuitry is provided for selectively sharing signals (e.g., control-type signals) among these channels in groupings of various size so that the device can better support communication protocols that require various numbers of channels (e.g., one channel operating relatively independently, four channels working together, eight channels working together, etc.). The signals shared may include a clock signal, a FIFO write enable signal, a FIFO read enable signal, or the like. The circuit arrangements are preferably modular (i.e., the same or substantially the same from one channel to the next and/or from one group of channels to the next) to facilitate such things as circuit design and verification.

Abstract: A method and apparatus for reducing block related artifacts in video are disclosed. A boundary is defined in a video frame between at least two or more sub-blocks where each of the sub-blocks contains a predetermined number of pixels. Pixels adjacent to the boundaries of the sub-blocks may be filtered to reduce blocking artifacts in the video. Pixel video values such as luma and chroma values may be utilized as input values to an anti-block filter. Average mean and average variance of the pixel video values in a sub-block are used to determined when anti-block filtering is applied. Pixels adjacent to the sub-block boundaries are filtered with an anti-block filtering algorithm in the event a predetermined condition is satisfied where the condition may be based upon the calculated average mean and average variance values. The filtering algorithm may include recalculating a pixel video value for pixels adjacent the sub-block boundaries. The invention may be utilized, for example, in converting MPEG-1 video to MPEG-2, and may be used in video devices such as VCD or DVD players, camcorders, etc. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other researcher to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

Abstract: A multimedia decoder is provided that inserts synchronization words into elementary linear pulse-code modulation (LPCM) audio bitstreams. In one embodiment, the multimedia decoder includes a pre-parser, a memory, and an audio decoder module. The pre-parser receives a multimedia bitstream and separates it into an audio substream and a video substream, and inserts a synchronization words before each data packet in the audio substream while forming it into an elementary bitstream. The memory is coupled to the pre-parser to buffer the elementary audio bitstream, and the audio decoder module is coupled to the memory to retrieve the elementary audio bitstream and convert it into a digital audio signal. The inserted synchronization word may comprise between from four to ten bytes in length. In one particular implementation, the inserted synchronization word includes the ASCII representation of the letters LSILOGIC. The insertion and subsequent detection of a synchronization word in the elementary audio bitstream advantageously provides for robust synchronization in the presence of bitstream corruption while maintaining multimedia decoder modularity.

Abstract: An audio decoder which includes a coefficient memory and an arithmetic logic unit (ALU) can implement an efficient method for calculating a gain value specified by a range control field. In one embodiment, the audio decoder comprises coefficient memory, an ALU, frame control logic, and ALU control logic. The frame control logic extracts a range control field value from an audio packet header and provides it to the ALU control logic. The ALU control logic takes the binary representation of the range control field value and uses it to provide a sequence of addresses to the coefficient memory. In response to the sequence of addresses, the coefficient memory provides a sequence of pre-calculated factors to the ALU. The ALU control logic further directs the ALU to determine the product of the pre-calculated factors in the sequence. As a final step in finding the gain value, the ALU control logic may provide a shift instruction to the ALU. In one specific implementation, there is a maximum of three pre-calculated factors and one shift instruction required for one calculation of the gain value, and a required storage of only seven non-unity pre-calculated factors.

Abstract: An audio decoder converts a linear PCM audio data packet into two concurrently provided digital audio sample sequences: a high-quality sequence and a decimated sequence. In one embodiment, the audio decoder is part of an audio system that further includes two audio devices. The first audio device is configured to produce an audio signal from a 96 kHz sequence, and the second audio device expects a 48 kHz sequence. The audio decoder includes an input interface, an arithmetic logic unit (ALU), and two output buffers. The input interface is configured to receive a linear PCM audio data packet and to reconfigure bytes as necessary to reconstruct a sequence of unscaled audio samples. The ALU multiplies each of the unscaled audio samples by a gain factor and buffers the resulting scaled audio sample sequence in a first output buffer. After samples for two sampling instants have been processed, the ALU then retrieves a string of samples from the first output buffer, multiplies them by decimation filter coefficients, and adds the products to form decimation samples for one sampling instant. The decimation samples form a decimated audio sequence which is buffered in the second output buffer. The first output buffer provides the 96 kHz sequence to the first audio device, and the second output buffer provides the 48 kHz sequence to the second audio device. The sharing of the ALU between the scaling and decimation operations advantageously provides a versatile decoder at a minimal cost.
