摘要： A method and system for an L.sub.2 norm operation are provided. A sequence of input signals is converted to a sequence of log signals. The sequence of log signals is distributed through a data pipeline to a plurality of processing elements which effectively multiply each log signal by a factor of two to produce a plurality of term signals. The term signals are then converted to inverse-log signals which are summed to produce a feedback signal. The square-root of the feedback signal is computed to generate an output signal. The log/inverse-log conversions of signals are based on estimating a log/inverse-log function using a second-order polynomial. The L.sub.2 norm operation can be performed using the distance between two vectors.

摘要： A pixel map signal is converted into a coefficient signal of block coefficient signals, each representing the pixels in a pixel map block (420) in a pixel map (410) with the coefficients in a hybrid polynomial. The coefficient signal is quantized by dividing each of the coefficient values in each of the block coefficient signals by quantization factors to produce quantized coefficient values which replace the coefficient values. Block coefficient signals which represent an edge block (424) in the pixel map (410) are divided by larger quantization factors than block coefficient signals which represent a center block (422) in the pixel map (410). As a result, smaller quantized coefficient values are obtained so that block coefficient signals which represent an edge block (424) are compressed to a greater extent than block coefficient signals that represent a center block (422) in the pixel map (410).

摘要： Boundaries of spoken sounds in continuous speech are identified by classifying delimitative sounds to provide improved performance in a speech-recognition system. Delimitative sounds, those portions of continuous speech that occur between two spoken sounds, are recognized by the same method used to recognize spoken sounds. Recognition of delimitative sounds is accomplished by training a learning machine to act as a classifier which implements a discriminant function based on a polynomial expansion.
