The dedicated remote system upgrade circuitry in Stratix III devices
manage remote configuration and provides error detection, recovery,
and status information. User logic or a Nios II processor implemented in
the Stratix III device logic array provides access to the remote
configuration data source and an interface to the system's configuration
memory.
Stratix III devices have remote system upgrade processes that involves
the following steps:

configuration updates. (The numbers in the figure below coincide with
the steps above.)
A Nios II processor (or user logic) implemented in the Stratix III
device logic array receives new configuration data from a remote
location. The connection to the remote source uses a communication
protocol such as the transmission control protocol/Internet protocol
(TCP/IP), peripheral component interconnect (PCI), user datagram
protocol (UDP), universal asynchronous receiver/transmitter
(UART), or a proprietary interface.
The Nios II processor (or user logic) stores this new configuration
data in non-volatile configuration memory.
The Nios II processor (or user logic) initiates a reconfiguration cycle
with the new or updated configuration data.
The dedicated remote system upgrade circuitry detects and recovers
from any error(s) that might occur during or after the
reconfiguration cycle, and provides error status information to the
user design.
