Altera Corporation
Cyclone III devices support remote system upgrade in AS and AP configuration
schemes. Cyclone III LS devices support remote system upgrade in the AS
configuration scheme only. Remote system upgrade can also be implemented with
advanced Cyclone III features such as real-time decompression of configuration data
in the AS configuration scheme.

The dedicated remote system upgrade circuitry in Cyclone III device family manages
remote configuration and provides error detection, recovery, and status information.
User logic or a Nios
array provides access to the remote configuration data source and an interface to the
configuration memory.
Configuration memory refers to serial configuration devices (EPCS) or supported
parallel flash memory, and depends on the configuration scheme that you use.
The remote system upgrade process of Cyclone III device family involves the
following steps:
1. A Nios II processor (or user logic) implemented in the Cyclone III device family
2. The Nios II processor (or user logic) writes this new configuration data into a
3. The Nios II processor (or user logic) starts a reconfiguration cycle with the new or
4. The dedicated remote system upgrade circuitry detects and recovers from any
The serial configuration device uses the AS configuration scheme to configure
Cyclone III or Cyclone III LS devices
The supported parallel flash uses the AP configuration scheme to configure
Cyclone III devices
Remote system upgrade is not supported in the multi-device configuration chain
for any configuration scheme.
logic array receives new configuration data from a remote location. The connection
to the remote source is a communication protocol such as the transmission control

user datagram protocol (UDP), universal asynchronous receiver/transmitter
(UART), or a proprietary interface.
