Abstract

LA INVENCION SE REFIERE A UNA UNIDAD DE CONTROL DE COMUNICACION Y UN PROCEDIMIENTO PARA LA TRANSMISION DE MENSAJES DENTRO DE UNA ARQUITECTURA DE ORDENADOR DISTRIBUIDA EN TIEMPO REAL, CONSISTIENDO EN UNA PLURALIDAD DE UNIDADES TOLERANTES DE ERROR EN DONDE LA INFORMACION A SER TRANSMITIDA CONSISTE EN UN CAMPO (K) DE CONTROL, UN CAMPO (D) DE DATOS Y UN CAMPO CRC (CYCLICREDUNDANCY CHECK) (CRC). EL CAMPO CRC CONSISTE EN INFORMACION STANDARD A PARTIR DE LA CONCENTRACION DEL CAMPO (K) DE CONTROL, EL CAMPO (D) DE DATOS Y EL ESTADO INTERNO LOCAL DE UNA UNIDAD DE CONTROL DE COMUNICACIONES DE TRANSMISION. LA SITUACION INTERNA LOCAL DE UNA UNIDAD DE CONTROL DE ESTE TIPO ESTA PROVISTA POR MEDIO DE LA COMBINACION DEL TIEMPO COMPLETO CON UNA OBSERVACION DE CAMPO DONDE LA UNIDAD DE TOLERANCIA DE ERROR SE LOCALIZA EN UN BIT DADO, CUYA SITUACION VERDAD DE LA OPERACION CORRECTA INDICADA Y LA SITUACION ERROR DE ESTAS INDICACIONES SUMINISTRAN UNA SITUACION DE ERROR, DE TAL FORMA QUE UNA UNIDAD DE CONTROL DE RECEPCION PUEDE, POR MEDIO DE PRUEBA EN UN ELEMENTO DESCONOCIDO DE INFORMACION, RECONOCER AMBAS INFORMACIONES CORRECTAS Y UNA DIFERENCIA ENTRE EL ESTADO INTERNO DE LA TRANSMISION Y DE LA UNIDAD DE CONTROL DE COMUNICACION DE RECEPCION.
