A device includes a Coordinate Rotation Digital Computer (CORDIC), a memory, a first Direct Memory Access (DMA) engine, and a second DMA engine. The memory stores an array of calculation data sets and an array of result data sets corresponding to the calculation data sets. The first DMA engine copies each data set of the array of calculation data sets from the memory to the CORDIC. The second DMA engine copies each result data set of the array of result data sets from the CORDIC to the memory and generates a trigger in response to copying a final result data set of the array of result data sets to the memory.

In at least one illustrative embodiment, an adjustable joint comprises a housing, a pair of wedges arranged in the housing, and a threaded fastener engaged with at least one of the pair of wedges. The housing may include a first cavity that is sized to receive a spherical end of a shaft and a second cavity that is sized to receive a tube. The pair of wedges may be arranged between the first and the second cavities. The threaded fastener may be configured to (i) move the pair of wedges away from one another when rotated in a first direction and (ii) move the pair of wedges toward one another when rotated in a second direction opposite the first direction.

An apparatus configured to filter video information according to certain aspects includes a memory unit and a processor in communication with the memory unit. The memory unit stores video information comprising at least two adjacent video blocks, each video block comprising a plurality of video samples, and each video sample having a bit depth. The processor determines a filtered video sample based at least in part on a video sample and an adjustment value. The processor determines the adjustment value at least in part from an input with a limited bit depth. The input is determined from a set of one or more video samples, and its bit depth is limited such that it is less than the bit depth of the one or more video samples.

Techniques for performing sample adaptive offset (SAO) and adaptive loop filter (ALF) processes in a video coding process are described. The SAO and ALF processes may be combined. In one example, the determination of offset values for a SAO filter process may be based on classifications used in an ALF process. In one example, an ALF classification that indicates a particular directional characteristic of a video block may be used to determine how and whether an SAO filter process is applied to each sample within the video block.

The techniques of this disclosure are generally related to parallel coding of video units that reside along rows or columns of blocks in largest coding units. For example, the techniques include removing intra-prediction dependencies between two video units in different rows or columns to allow for parallel coding of rows or columns of the video units.

Similarities between simplex projection with upper bounds and Lprojection are explored. Criteria for a-priori determination of sequence in which various constraints become active are derived, and this sequence is used to develop efficient algorithms for projecting a vector onto the L-ball while observing box constraints. Three projection methods are presented. The first projection method performs exact projection in O(n) worst case complexity, where n is the space dimension. Using a novel criteria for ordering constraints, the second projection method has a worst case complexity of O(n log n). The third projection method is a worst case linear time algorithm having O(n) complexity. The upper bounds defined for the projected entries guide the L-ball projection to more meaningful predictions.

This invention decoded encoded speech using alternative parameters upon detection of a lost packet. Upon detection of a first good packet following packet loss, this invention uses second alternative parameters intermediate between the default parameters and the alternative parameters for a predetermined interval. Thereafter the invention reverts to the default parameters. This minimizes glitches in the decoded speech upon packet loss. This invention is suitable for use in decoding speech data encoded in the CCITT Recommendation G.726 ADPCM based speech coding standard.

This invention is a new approach for the image watermarking in the wavelet transform domain based on sequency of the host and watermark image. For each sub-band a first transform level of the host image is thresholded and binarized. Sequencies of thresholded and binarized data host image are compared with sequencies of the discrete wavelet transformed watermark image to form a watermarking sequency mask. The watermarked wavelet domain data is formed by combining data elements of the discrete wavelet transformed host image with corresponding data elements of the wavelet transformed watermark image as filtered by the watermarking mask. A reverse process can extract the watermark with a high degree of accuracy even after attack upon the watermarked host image.
