ABSTRACT:
A data management system includes a first processing unit, a second processing unit operating independently of the first processing unit, a dual-port memory connected between the first processing unit and the second processing unit and used to transfer data between the first processing unit and the second processing unit, a first data holding unit for storing data used for processing in the first processing unit, and a second data holding unit for storing data used for processing in the second processing unit. The data stored in one of the first and second data holding units is transferred to the other one of the first and second data holding units via the dual-port memory when a failure occurs in one of the first and second processing units is eliminated, so that the first and second holding units store identical data.
