Abstract:
An assembly, comprising:a codebook including a plurality of codebook vectors, each codebook vector having a respective identification code associated therewith;a first circuit arranged to determine a distance value between an input vector and each respective one of said plurality of codebook vectors and to provide a respective distance signal representative thereof;a second circuit, responsive to said distance signals provided by said first circuit, for determining the smallest distance value and identifying the codebook vector associated therewith; anda third circuit arranged to provide the identification code associated with the codebook vector identified by said second circuit in connection with the smallest distance value determination;said second circuit further comprising a plurality of logic circuits arranged in a cascade configuration, each logic circuit having an input side and an output side and respectively including at least one logic device, the output side of one logic circuit being coupled to the input side of a next logic circuit in said cascade configuration;each respective logic circuit being responsive to a respective plurality of said distance signals provided at its input side for determining the smallest distance value and providing the smallest distance value distance signal at its output side.
