This section describes the implementation of the Stratix IV remote system upgrade
dedicated circuitry. The remote system upgrade circuitry is implemented in hard
logic. This dedicated circuitry interfaces to the user-defined factory and application
configurations implemented in the Stratix IV device logic array to provide the
complete remote configuration solution. The remote system upgrade circuitry
contains the remote system upgrade registers, a watchdog timer, and a state machine
that controls those components.
