Abstract

LA INVENCION SE REFIERE A UNA DISPOSICION CON PARTICIPANTES (MP1, MP2, SP1, SP2) DE BUS PASIVOS Y ACTIVOS MULTIPLES, CADA UNO DE LOS CUALES ESTA LOCALIZADO EN UNA MEMORIA (S1, S2, SS1, SS2), CON SU PROPIA ZONA DE MEMORIA (SB1, SB2, SB3, SB4), DONDE CADA UNO DE LOS UTILIZADORES BUS (MP1, MP2, SP1, SP2) HA CONSEGUIDO ACCESO A SU PROPIA AREA DE MEMORIA (SB1, SB2, SB3, SB4) Y CADA PARTICIPANTE (MP1, MP2) DE BUS ACTIVO DISPONE DE ACCESO ESCRITO A CADA AREA (SB1, SB2, SB3, SB4) DE MEMORIA. UNA LINEA (ML) DE CONTROL ESTA PREVISTA PARA ENVIAR UNA SEÑAL (SR) INDICATIVA QUE INDICA AL PARTICIPANTE (MP1, MP2) DE BUS ACTIVO EL ACCESO A LAS AREAS (SB1, SB2, SB3, SB4) DE MEMORIA SIN LOS DATOS EN LAS AREAS (SB1, SB2, SB3, SB4) DE MEMORIA, DADO QUE LA SEÑAL (SR) DE RESPUESTA DISPONE DE UNA SITUACION DOMINANTE Y RECESIVA Y, FUERA DE LO CICLOS DE ACCESO DE TODOS LOS PARTICIPANTES BUS, PRODUCE UNA SITUACION DOMINANTE, DURANTE UN CICLO DE ACCESO A LAS AREAS (SB1, SB2, SB3, SB4) DE MEMORIA SOLAMENTE DE LOS PARTICIPANTES (MP1, MP2, SP1, SP2) DE BUS EN CUYAS AREAS (SB1, SB2, SB3, SB4) DE MEMORIA LOS DATOS NO HAN SIDO TODAVIA ESCRITOS PARA PRODUCIR UNA SEÑAL DE ESTE TIPO. LA INVENCION DR UTILIZA EN SISTEMAS DE AUTOMOCION.
