ABSTRACT:
A method of determining which search target vector from a plurality of search target vectors is closest to an input vector. A device to perform the method is also disclosed. Rather then perform a distance calculation for each and every search target vector, the disclosed method narrows the field of the search through a simple process. The input vector is compared to each search target vector, and a mask is used to evaluate the result of the comparison. Then, the actual distance is calculated for those search target vectors within a search range of the input vector.
