Abstract

LAS IMAGENES ACTUALIZADAS DE MENSAJES PASAN ENTRE PROCESADORES DIGITALES ASINCRONOS QUE UTILIZAN MEMORIA COMPARTIDA DE DOBLE ACCESO. CUANDO UNO DE LOS PROCESADORES ES UN CONTROLADOR DE UN CANAL DE TRANSMISION DE DATOS QUE TRANSPORTA N MENSAJES, EN EL ESPACIO LIBRE DE MEMORIA COMPARTIDA EXISTEN 2N + 1 MEMORIAS INTERMEDIAS, DOS DE LAS CUALES ESTAN ASIGNADAS A CADA MENSAJE DURANTE TODO EL TIEMPO Y UNA MEMORIA INTERMEDIA COMUN SIRVE COMO LA TERCERA MEMORIA COMPARTIDA PARA TODOS LOS OTROS MENSAJES. CUANDO LAS MEMORIAS ENLAZADAS EN LA MEMORIA LOCAL DE UN CONTROLADOR RECIBEN ACTUALIZACIONES DE MENSAJE DE UNA VIA DE DATOS, SE ASIGNAN DOS MEMORIAS INTERMEDIAS EN LA MEMORIA COMPARTIDA A CADA MENSAJE, SIRVIENDO COMO TERCERA MEMORIA UNA MEMORIA COMPARTIDA EN LA MEMORIA LOCAL DEL CONTROLADOR. LAS MEMORIAS INTERMEDIAS CONTIENEN LAS ACTUALIZACIONES DEL MENSAJE Y PASAN ENTRE PROCESADORES MEDIANTE UN CONJUNTO DE ESTADO DE MEMORIAS INTERMEDIAS EN LA MEMORIA COMPARTIDA. UN CONTROL SEMAFORICO EN EL CONJUNTO HACE QUE SOLO UN PROCESADOR AL TIEMPO ASIGNE O LIBERE LAS MEMORIAS INTERMEDIAS.
