Remote System Upgrade

May 2013

Altera Corporation

Cyclone IV Device Handbook,

Volume 1

When Cyclone IV devices successfully load the application configuration, they enter

user mode. In user mode, the soft logic (the Nios II processor or state machine and the

remote communication interface) assists the Cyclone IV 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, determines the valid application configuration

to load, writes the remote system upgrade control register accordingly, and starts

system reconfiguration.
