Arria II devices feature dedicated remote system upgrade circuitry. Soft logic (either

download a new configuration image from a remote location, store it in configuration
memory, and direct the dedicated remote system upgrade circuitry to start a
reconfiguration cycle. The dedicated circuitry performs error detection during and
after the configuration process, recovers from any error condition by reverting back to
a safe configuration image, and provides error status information.
Remote system upgrades are supported in AS configuration schemes for Arria II GX
devices and in fast AS configuration schemes for Arria II GZ devices. You can also
implement remote system upgrades in conjunction with advanced Arria II features
such as real-time decompression of configuration data and design security using the
advanced encryption standard (AES) for secure and efficient field upgrades. The
largest serial configuration device currently supports 128 MBits of configuration
bitstream.
Arria II devices only support remote system upgrade in the single device fast AS
configuration scheme. Because the largest serial configuration device currently
supports 128 Mbits of configuration bitstream, the remote system upgrade feature is
not supported in EP2AGZ300, EP2AGZ350, and larger devices.
The remote system upgrade feature is not supported in a multi-device chain.
The dedicated remote system upgrade circuitry in Arria II devices manages remote
configuration and provides error detection, recovery, and status information. User
logic or a Nios II processor implemented in the Arria II device logic array provides
access to the remote configuration data source and an interface to the system’s
configuration memory.
Arria II devices have remote system upgrade processes that involve the following
steps:
1. A Nios II processor (or user logic) implemented in the Arria II device logic array
2. The Nios II processor (or user logic) stores this new configuration data in
3. The Nios II processor (or user logic) starts a reconfiguration cycle with the new or

remote source uses a communication protocol such as TCP/IP, PCI, user datagram
protocol (UDP), UART, or a proprietary interface.
