    摘要: An anti-lock braking system for a vehicle having a plurality of wheels, and a braking system that includes a brake for braking at least one of the plurality of wheels and a brake valve for controlling a braking pressure in the brake in response to a brake valve signal, includes a plurality of wheel speed sensors for generating a plurality of input signals. A polynomial processor, in communication with the plurality of wheel speed sensors, generates a control signal based on a nonlinear polynomial function of the input signal. A post-processor generates the Brake valve signal based on the control signal so as to provide cyclic control of the braking pressure in the brake.

    摘要: A circuit and method for computing an exponential signal x.sup.g is provided. The circuit includes a logarithm converter which converts an input signal to binary word that represents the logarithm of an input signal x. A first shift register shifts the binary word in a bit-wise fashion to produce a first intermediate value; while a second shift register shifts the binary word in a bit-wise fashion to produce a second intermediate value. The shift registers may be implemented using multiplexers. The shifting operations are equivalent to multiplying the intermediate values by a factor which is a power of two. The first intermediate value is either added to or subtracted from the second intermediate value to produce a combined value. An inverse-logarithm converter converts the combined value to the exponential signal.

    摘要: In a method and system for storing a plurality of data blocks in a memory device, blocks of data elements are stored in a two-dimensional address space such that blocks overlap in the address space. The data elements may be digital words which represent exponents of a polynomial expansion. An overlapping data block is segmented into sub-blocks which are separated by null regions. Common data elements that are shared among the blocks are non-redundantly stored in the memory device.

    摘要: A system for recognizing spoken sounds from continuous speech includes a plurality of classifiers and a selector. Each of the classifiers implements a discriminant function which is based on a polynomial expansion. By determining the polynomial coefficients of a discriminant function, the corresponding classifier is tuned to classify a specific spoken sound. The selector utilizes the classifier outputs to identify the spoken sounds. A method of using the system is also provided.
