Abstract

Various calculations of matrices and vectors are used in many digital signal processing systems. Although the calculation simply repeats multiplication and addition, the reiteration processing is usually heavy. Therefore, in order to perform the calculations with high speed, it is necessary to apply parallel precessing. Although there is an issue with increased circuit area in the case of digital LSI, the proposed analog circuit can realize multiplication and addition simultaneously with a simple structure which arranges capacitors in a matrix form. Furthermore, a vowel speech recognition system is designed using this circuit
