This section describes the implementation of the Cyclone IV device remote system
upgrade dedicated circuitry. The remote system upgrade circuitry is implemented in
hard logic. This dedicated circuitry interfaces with the user-defined factory
application configurations implemented in the Cyclone 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 state
machines that control those components.
