摘要： A current state of an item being tracked by an item-tracking system may be determined using prior state information about the item. To ensure proper temporal order of the state information, software events triggered by physical events associated with the item are received from a reader at an event interpretation system. A database or queue within the event interpretation system holds the software events for a delay time determined by a maximum transmission delay time of the software events. A sorter within the event interpretation system orders the software events relative to one another so as to correspond to an order of the physical events. An association model of the event interpretation system may determine state information related to the item for storage in a state information database. Accordingly, system exceptions in the item tracking system may be reduced, and an accuracy and reliability of the system may be improved.

摘要： Methods and apparatus, including computer program products, for providing multiple enterprises real-time access to information about items in a supply chain. Tags bound to items are read and information read from the tags and location information about the tags is provided by at least two enterprises and used to maintain disposition information about the items, which is made visible to enterprises in the supply chain. The tags can be radio-frequency identification tags having each having an ePC (electronic product code) as unique tag identifier. Visibility of the disposition information can be controlled through authorization. Visible information can include relationships between particular items and business documents such as order and shipping documents. With shipping documents visible, information read from item tags can be used to confirm the identify or completeness of a shipment.

摘要： Gamma correction or other power functions are generated for correcting the light intensity for digital pixels. Two levels of mapping of segments are preformed to reduce the total number of segments for a given precision. The range of inputs is divided into successively smaller segments. Each segment is smaller than the next by a factor of 1/a for a first or primary level, or 1/b for a second level of segments. All inputs are mapped or scaled up to the input range of the largest segment in the primary level. Then the largest primary segment is further divided into several second-level segments, and the input is again mapped or scaled into the largest of the second-level segments. Gamma correction is performed on the input scaled into the largest second-level segment. A linear approximation within the largest second-level segment is used. The result is de-mapped or scaled down from the largest second-level segment to the actual second-level segment, then it is scaled down from the largest primary-level segment to the actual primary-level segment for the original input. Smaller priority encoders and shifters and simplified de-mapping circuits can be used, saving logic.

摘要： A specialized Sum-of-Absolute-Difference (SAD) calculator for motion estimation uses inversion rather than 2's complementing. The absolute-value operation of each pixel-pair difference is performed by a bit-wise inversion rather than a complement. This reduces delay since the adder/incrementer propagation is eliminated. The increment needed to adjust for inversion rather than 2's complementing is accomplished by using the carry inputs to the summing and final adders that generate the sum of the absolute differences. When 2-input final adders are used for summing, a total of k−1 adders are used to sum k absolute differences. One additional increment is needed since only k−1 adders are available. A reduced half-adder rather than a full adder is inserted between the summing and final adder for this remaining increment. Propagation of carries between bit positions in a full adder can be avoided using the half adder. The final adder generates the final sum (the SAD) by adding the sum and carry bits from the half-adder array and propagating the carries.

摘要翻译： 用于运动估计的专门的绝对差值（SAD）计算器使用反演而不是2的补码。 每个像素对差的绝对值运算通过逐位倒置而不是补码来执行。 这减少了延迟，因为加法器/递增器传播被消除。 通过使用产生绝对差的和的求和和最终加法器的进位输入来实现调整反转而不是2的补码所需的增量。 当使用2输入的最终加法器进行求和时，总共使用k-1个加法器来求和k个绝对差。 需要增加一个增量，因为只有k-1加法器可用。 在该剩余增量的加法和最终加法器之间插入减法的半加法器而不是全加器。 使用半加法器可以避免在全加器中的位位置之间传输的传播。 最后的加法器通过将加法和加和来自半加法器阵列的位进行加法生成最终和（SAD）并传播运算。

摘要： Digital-video compression uses motion vectors to encode movement of macroblocks from one image to another image in a sequence of images. Motion vectors are estimated using multiple levels of a picture, with higher levels having lower resolutions. Such hierarchical or pyramid motion estimation generates lower-resolution pictures from the full-resolution picture. A selected macroblock in a reference picture is compared to ranges in each successively-higher-resolution level. Rather than store the levels of a picture as full pixels, only a luminance Y component of a YUV pixel is stored and used for motion estimation. Further memory savings is achieved by reducing the width of the Y pixels from 8 bits to 6 bits for the top and bottom levels, and to 4 bits for intermediate levels of the picture. Pixels are reduced in width by storing only the most-significant-bits (MSBs), or by dithering. Motion estimation searches in each level are performed using pictures with reduced-width pixels. More bits are used in pixels for the top (lowest-resolution) and bottom (full resolution) level pictures for improved accuracy in the initial and final motion vectors. Fewer bits are used in pixels of the intermediate levels to reduced storage requirements.

摘要翻译： 数字视频压缩使用运动矢量来编码宏块从一幅图像到另一幅图像序列中的移动。 使用多个图像级别来估计运动矢量，其中较高的分辨率具有较低的分辨率。 这种分级或金字塔运动估计从全分辨率图像生成较低分辨率的图像。 将参考图像中的选定宏块与每个连续更高分辨率级别的范围进行比较。 不是将图像的电平存储为全像素，而是仅存储YUV像素的亮度Y分量并将其用于运动估计。 通过将Y像素的宽度从顶部和底部的8位减少到6位，并将图像的中间级别降低到4位来实现更多的存储器节省。 通过仅存储最高有效位（MSB）或抖动来减小像素的宽度。 使用具有较小宽度像素的图像来执行每个级别中的运动估计搜索。 更高的位用于顶部（最低分辨率）和底部（全分辨率）级别图像的像素，以提高初始和最终运动矢量的精度。 在中间级别的像素中使用较少的位来减少存储要求。

摘要： A 3D graphics accelerator operates in parallel with a host central processing unit (CPU). Software executing on the host CPU performs transformation and lighting operations on 3D-object primitives such as triangles, and generates gradients across the triangle for red, green, blue, Z-depth, alpha, fog, and specular color components. The gradients for texture attributes are also generated and sent to the graphics accelerator. Both the graphics accelerator and the CPU software perform triangle edge and span walking in synchronization to each other. The CPU software walks the triangle to interpolate non-texture color and depth attributes, while the graphics accelerator walks the triangle to interpolate texture attributes. The graphics accelerator performs a non-linear perspective correction and reads a texture pixel from a texture map. The texture pixel is combined with a color pixel that is received from the CPU software interpolation of non-texture attributes. Once the texture pixel from the graphics accelerator and the color pixel from the CPU software are sent to a blender in the graphics accelerator, both continue to interpolate the next pixel in the horizontal-line span, or move to a pixel in the next span. Both the CPU software and the graphics accelerator interpolate the same pixel at the same time. Using both the CPU and the graphics accelerator improves performance since both operate in parallel on the same pixel at the critical interpolation bottleneck.

摘要： A method of performing anti-aliasing on polynomial curves using only integer arithmetic. The anti-aliasing method includes the steps of: defining an polynomial equation of a curve, dividing grid units into an finite number of sub-intervals, associating a mix ratio to each of the sub-intervals, determining which sub-interval the curve bisects, assigning a mix ratio to each picture element bordering the grid unit according to the mix ratio associated with the sub-interval determined to be bisected by the curve.
