Abstract: A system and method for providing parallel result streams for database queries is provided. The system includes a network including a client, a server, and a database. The client executes an application and sends a query to the server. In response, the server compiles the query to produce a query plan, executes statements in the query plan and sends parallel result streams to the client.

Abstract: Circuit architecture for dynamic scene analysis uses a difference picture based technique wherein pixel values corresponding to the same position from previous and current frames are inputted to the system during each clock cycle. The difference picture is input to a connected component labeling algorithm in order to obtain the various connected components in the difference picture. A Sobel edge detector is applied to previous and current frame pixel values, and the resulting data stored in a buffer so that for each pixel, the connected component label of the difference picture, the Sobel edge value in the current frame, and the Sobel edge value in the previous frame are stored. The buffer supplies the data to a series of motion detection processors which are arranged in a systolic array. An alternative arrangement is to arrange the motion detection processors in parallel in a pipeline fashion with no feedback logic.

Abstract: A method and apparatus for compressing and decompressing text and image data by forming fixed-length codewords from a variable number of data symbols. Data symbols are shifted into registers in the first half of a buffer, while an uncompressed string of data symbols are shifted into registers in the second half of the buffer. A systolic array of processors compares each data symbol in the second half of the buffer with each data symbol in the first half of the buffer. Each processor compares pairs of data symbols, and selectively passes the data symbols to an adjacent processor. A fixed-length output is provided indicating the length and the starting point of the longest substring in the first half of the buffer that matches a substring from the second half of the buffer.
