Stratix III devices automatically load the factory configuration located at page address
zero. This user-designed factory configuration reads the remote system upgrade
status register to determine the reason for the reconfiguration. The factory
configuration then takes appropriate error recovery steps and writes to the remote
system upgrade control register to determine the next application configuration to be
loaded.
When Stratix III devices successfully load the application configuration, they enter
into user mode. In user mode, the soft logic (Nios II processor or state machine and
the remote communication interface) assists the Stratix III device in determining
when a remote system update is arriving. When a remote system update arrives, the
soft logic receives the incoming data, writes it to the configuration memory device,
and triggers the device to load the factory configuration. The factory configuration
reads the remote system upgrade status register and control register, determines the
valid application configuration to load, writes the remote system upgrade control
register accordingly, and initiates system reconfiguration.
This section explains the implementation of the Stratix III 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 III 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.
