Abstract

EN UNA DISPOSICION DE UNIDAD DE MEMORIA ACTIVA-STANDBY DOBLE (100) SE HACE UNA DETERMINACION DE INICIACION DE RESINCRONIZACION SOBRE UNA BASE DE INTERVALO DE CELULA POR INTERVALO DE CELULA BASADO EN LA IGUALDAD DE LOS CONTENIDOS DE LAS CELULAS DE COLAS CORRESPONDIENTES EN LA UNIDAD DE MEMORIA ACTIVA (101) O EN STANDBY (102). SI SE DA UNA DESIGUALDAD DE LOS CONTENIDOS DE LAS CELULAS DE LAS COLAS CORRESPONDIENTES EN LAS UNIDADES DE MEMORIA ACTIVO Y STANDBY DURANTE CUALQUIER INTERVALO DE CELULA SE PUEDE INICIAR EL RESINCRONIZACION. EN UNA REALIZACION, LAS LONGITUDES DE DATOS EN COLAS CORRESPONDIENTES, POR EJEMPLO EL NUMERO DE CELULAS ALMACENADAS EN LAS COLAS CORRESPONDIENTES, EN LA UNIDAD DE MEMORIA ACTIVA Y STANDBY SE COMPARAN (POR 105, 106, 107, 108) SOBRE UNA BASE DE INTERVALO DE CELULA POR INTERVALO DE CELULA. SI EL NUMERO DE CELULAS ALMACENADAS EN CUALQUIERA DE LAS COLAS ES DIFERENTES DEL NUMERO DE CELULAS EN SU COLA CORRESPONDIENTE EN LA OTRA UNIDAD DE MEMORIA DURANTE CUALQUIER INTERVALODE CELULA. LA RESINCRONIZACIONO DE LAS UNIDAD DE MEMORIA SE INICIA. LA OTRA REALIZACION DE LA INVENCION, LAS SALIDAS (114-115-1) DE COLAS CORRESPONDIENTES EN LA UNIDAD DE MEMORIA ACTIVA (114) Y LA UNIDAD DE MEMORIA STANBY (102) SE COMPARAN (POR 117) SOBRE UNA BASE INTERVALO DE CELULA POR INTERVALO DE CELULA. SI EL RESULTADO DE LA COMPARACION INDICA QUE UNO O MAS DE LAS SALIDAS DE COLAS EN UNA DE LAS UNIDADES DE MEMORIA ES DIFERENTE DE LA SALIDA DE LA COLA CORRESPONDIENTE EN LA OTRA UNIDAD DE MEMORIA, SE INICIA LA RESINCRONIZACION. LA FUERZA DE ESTE ULTIMO ALGORITMO DE COMPARACION SE REALZA RESTRINGIENDO LAS COMPARACIONES A LOS INTERVALOS DE CELULAS DURANTE LAS CUALES LAS SALIDAS DE COLA EN LAS UNIDAD DE MEMORIA ACTIVA Y STANDBY NO INCLUYEN CELULAS REACTIVAS. ADICIONALMENTE, LA FUERZA DE LA INICIACION DE RESINCRONIZACION SE REALZA EMPLEANDO SIMULTANEAMENTE TANTO LA COMPARACION DE LONGITUD DE CELULA EN LAS COLAS Y LA COMPARACION DE LOS CONTENIDOS DE SALIDA DE COLA PARA DETECTAR CUANDO INICIAR LA RESINCRONIZACION.
