Abstract
Viene descritta una unità di controllo e di elaborazione duplicata per apparati di telecomunicazioni costituita da due identiche unità di controllo tra loro interconnesse. Ciascuna unità di controllo (UCO, UC1) comprende una unità processore (UP0, UP1), che può risultare attiva oppure in standby, una memoria RAM dati periferica per i dati elaborati durante il funzionamento, e più circuiti periferici connessi al resto dell'apparato. Una EPROM (CCLO, CCL1) in ciascuna unità processore contiene il firmware di selezione copia. La RAM dati e i circuiti periferici includono un rispettivo circuito di accesso a doppia porta (ACCO, ACC1) che consente l'accesso selettivo al solo processore attivo. Quest'ultimo esegue i cicli di scrittura in modo sincrono su entrambe le RAM dati duplicate, consentendo un rapido recupero del sincronismo operativo da parte dell'unità processore di riserva (standby), dopo commutazione per guasto dell'unità processore attiva (fig.2).
