Remote System Upgrade
Functional Description
Cyclone IV Device Handbook, Volume 1

Cyclone IV devices support remote system upgrade in AS and AP configuration
schemes. You can also implement remote system upgrade with advanced Cyclone IV
features such as real-time decompression of configuration data in the AS
configuration scheme.
Remote system upgrade is not supported in a multi-device configuration chain for
any configuration scheme.
The dedicated remote system upgrade circuitry in Cyclone IV devices manages
remote configuration and provides error detection, recovery, and status information.
A Nios
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, depending on the configuration scheme that is used.
The remote system upgrade process of the Cyclone IV device consists of the following
steps:
1. A Nios II processor (or user logic) implemented in the Cyclone IV device logic
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
