| Abstract: | The hard real time dual systems are applied in crucial tasks widely. The common problem they face is how to guarantee the high availability and the high response time. A full discussion of the key problems in hard real time dual system is presented, including the definition of system architecture, fault detection and state transition. The practice shows that the solution can meet the requirement of high availability and hard real time, and the achievement is outstanding. |
