Abstract

Un sistema de tratamiento de datos. Una interconexión para elementos en un sistema de tratamiento de datos transmite señales de sincronismo que establecen intervalos de sincronismo. Cada elemento está habilitado para transferir información sobre la interconexión por un sistema de control de acceso que responde a las señales de sincronismo y señales de control de acceso procedentes de la interconexión. La información es transferida durante un intervalo de sincronismo en respuesta a las señales de sincronismo y a las señales de control de acceso. Son transferidas señales de confirmación durante un intervalo de sincronismo subsiguiente en respuesta a la transferencia de información y a las señales de sincronismo.
