Abstract: Systems and methods are provided for writing code to access data arrays. One aspect provides a method of accessing a memory array. Data is provided within a one-dimensional array of allocated memory. A dimensional dynamic overlay is declared from within a block of statements, and the declaration initializes various attributes within an array attribute storage object. The data is accessed from within the block of statements as a dimensional indexed array using the array attribute storage object. Another aspect provides a method of creating and accessing a dimensional dynamic array. A dimensional dynamic array is declared from within a block of statements, and memory storage for the array is dynamically allocated. A dynamic overlay storage object is also provided and its attributes are initialized from the dynamic array declaration. The data is accessed as a dimensional indexed array from within the block of statements using the array attribute storage object.

Abstract: A method is comprised of inputting a comparand word to a plurality of hash circuits, each hash circuit being responsive to a different portion of the comparand word. The hash circuits output a hash signal which is used to enable or precharge portions of a CAM. The comparand word is also input to the CAM. The CAM compares the comparand word in the precharged portions of the CAM and outputs information responsive to the comparing step. When used to process Internet addresses, the information output may be port information or an index from which port information may be located. A circuit is also disclosed as is a method of initializing the circuit.

Abstract: A rolling shutter digital camera. Each photographic image of a given exposure duration is captured as a multi-frame burst of frames each having a shorter exposure duration to minimize motion blur and to reduce sensor noise by averaging. Each frame is quantized into swaths, captured sequentially by the rolling shutter. Swaths of the first frames are analyzed to select a set of best motion detection reference regions. Swaths of subsequent frames are analyzed versus only those regions, to reduce required computation, and are re-registered accordingly. Corresponding swaths of each frame are accumulated. The accumulator is normalized to the desired bit depth and written as the final image. Averaging of the multiple frames is improved by re-registering swaths rather than entire frames, because of the time delta caused by the rolling shutter. Computation is further reduced by selecting candidate points only along a key line of each swath of the first frame, and still further by pre-limiting the search by using a thumbnail version of the first frame to cull most candidate points. Thresholds are used to ensure adequate motion detection regions are used for each swath.

Abstract translation: 滚动快门数码相机。 给定曝光持续时间的每个摄影图像被捕获为具有较短曝光持续时间的帧的多帧突发，以最小化运动模糊并且通过平均来降低传感器噪声。 每个帧被量化成条，由滚动快门顺序捕获。 分析第一帧的幅面以选择一组最佳运动检测参考区域。 分析后续帧的幅面，而不仅仅是那些区域，以减少所需的计算，并相应地重新注册。 每个帧的相应条带被累积。 将累加器归一化为所需的位深度并写入最终图像。 由于由滚动快门引起的时间增量，可以通过重新排列条带而不是整个帧来改善多个帧的平均。 通过仅沿着第一帧的每个条带的键线选择候选点进一步减少计算，并且还通过使用第一帧的缩略图版本预先限制搜索以剔除大多数候选点。 阈值用于确保为每个条带使用足够的运动检测区域。

Abstract: A resampling circuit and method where input sample values for samples arranged along a row of a source image are received by a row resampling circuit. The row resampling circuit calculates row output values which are provided to a column resampling circuit that calculates output sample values therefrom. The column resampling circuit includes a shift register that receives the row output values and shifts the row output values through the shift register as the row output samples are calculated. The shift register has a plurality of evenly spaced sample output terminals from which the row output values are sampled by an interpolation circuit for calculation of the output sample values.

Abstract: A method and system for determining a transition model between input pixel samples from which output sample values are calculated based on various relative background and brightness conditions of the input pixel samples. A brightness condition is determined from the input sample values associated with the input pixel samples. A first transition model that preserves a constant luminance is used where the brightness condition is indicative of light isolated pixels and a second transition model that preserves a constant darkness is used where the brightness condition is indicative of dark isolated pixels. The resampling circuit may also use alternative models for other brightness conditions, such as for pixel transitions without any emphasis or alternating pixels. The resampling circuit may also perform modified operations for pixels arranged in a diagonal fashion.

Abstract: A method of encrypted communication including creating a message and looking up a public key of a recipient. Then, encoding the message via a first encoding process using a first portion of the public key to generated an intermediate encoded message. The intermediate encoded message is encoded via a second encoding process using a second portion of the public key to generate a final encoded message. Then, the final encoded message is sent to a recipient. The public key may have a first key portion, a second key portion, and a third key portion, with the third key portion containing the encoded identity of a data element needed to decode a message encoded with the second key portion. The third key portion is encoded with the public key of a monitoring authority to enable the monitoring authority to more readily decode transmitted messages.

Abstract: Composite video timing adjustments using digital resampling provides precise sub-pixel timing relative to a timing reference with a single video master clock. A digital resampler interpolates an input digital composite video signal as a function of a phase offset input which defines a fractional clock period of the video master clock derived from the timing reference. The sub-pixel offset digital composite video signal also may be adjusted by integer multiples of the video master clock period using a FIFO memory. The final timing adjusted digital composite video signal then is input to an analog reconstruction circuit to provide an output analog composite video signal that is precisely timed to the timing reference.
