Abstract :
In this paper we present sequential, parallel and pipeline structures for the computation of a vectorial quantifier that may be used as a classifier in speech recognition systems. The structures are modeled in VHDL and can be used as embedded cores in different designs. The models have been implemented by FPGAs and the hardware demands on resources, frequency and power dissipation have also been evaluated.
