Предложенный подход проектирования умножителя на кватернион-константу позволяет достигать максимальной производительности схемы умножителя при скромном использовании ресурсов, например FPGA.</p></abstract><trans-abstract xml:lang="en"><p>The article contains a number of solutions for the key element of paraunitary filter banks based on quaternionic algebra (Q-PUBF) – the multiplier of quaternions with usage of CORDIC (Coordinate Rotation Digital Computer) techniques for the fixed angle of rotation where, unlike known solutions, 4D rotation control parameters are represented by nonlinear function of shifts number of input operands of the microrotation operation. Suggested approach of the multiplier designing on a quaternion-constant allows reaching the maximum performance of the multiplier scheme with low use of resources, for example, of FPGA.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Кантор, И.Л.
