APPARATUS AND METHOD FOR MANAGING ACCESS RIGHT OF MASTER IN BACKPLANE WITH MULTI-MASTER, AND BACKPLANE SYSTEM USING THEREOF

摘要

PURPOSE: An apparatus, a method for managing the access right of a master, and a back plane system are provided to increase the availability and stability of a backplane system by using masters in a backplane system of a master-slave structure. CONSTITUTION: A timer(204) counts waiting time of a master which requests access right for data transfer. A signal sensing unit(202) senses a data signal of the other master transmitted to a backplane(210). A switching unit(206) is switched according to a sensing result of the signal sensing unit. The data is transmitted to the backplane.
