Abstract

SE PRESENTA UN METODO Y APARATO PARA CALCULAR LA PROYECCION ESCALAR DE UN VECTOR SOBRE OTRO. EL APARATO COMPRENDE UN CIRCUITO MULTIPLICADOR (94) Y UN CIRCUITO SUMADOR (96). EL PRIMER CIRCUITO (94) MULTIPLICA UN VALOR REPRESENTATIVO DE UN PRIMER COMPONENTE DE UN PRIMER VECTOR POR UN VALOR REPRESENTATIVO DE UN PRIMER COMPONENTE DE UN SEGUNDO VECTOR PARA PROPORCIONAR UN PRIMER VALOR INTERMEDIO, Y MULTIPLICA UN VALOR REPRESENTATIVO DE UN SEGUNDO COMPONENTE DE UN PRIMER VECTOR POR UN VALOR REPRESENTATIVO DE UN SEGUNDO COMPONENTE DE UN SEGUNDO VECTOR PARA PROPORCIONAR UN SEGUNDO VALOR INTERMEDIO. EL CIRCUITO ADICIONADOR (96) SUMA LOS VALORES INTERMEDIOS PRIMERO Y SEGUNDO PARA PROPORCIONAR UN VALOR RESULTANTE REPRESENTATIVO DE LA PROYECCION ESCALAR DEL PRIMER VECTOR SOBRE EL SEGUNDO VECTOR. EL APARATO PUEDE ADEMAS COMPRENDER UN PRIMER CIRCUITO DE ALMACENAMIENTO (80,82), UN PRIMER CIRCUITO DE SELECCION (88), UN SEGUNDO CIRCUITO DE ALMACENAMIENTO (84,86) Y UN SEGUNDO CIRCUITO DE SELECCION (90). EL PRIMER CIRCUITO DE ALMACENAMIENTO (80,82) ALMACENA LOS VALORES REPRESENTATIVOS DE LOS COMPONENTES PRIMERO Y SEGUNDO DEL PRIMER VECTOR Y EL SEGUNDO (84,86) ALMACENA LOS VALORES REPRESENTATIVOS DE LOS COMPONENTES PRIMERO Y SEGUNDO DEL SEGUNDO VECTOR. LOS CIRCUITOS DE SELECCION (88,90) PROPORCIONAN UN SUMINISTRO ORDENADO DE ESTOS VALORES AL CIRCUITO MULTIPLICADOR (94).
