Remote System Upgrades
Arria II Device Handbook Volume 1: Device Interfaces and Integration
When multiple Arria II devices are cascaded, you can selectively enable the
compression feature for each device in the chain if you are using a serial configuration
scheme.
compression enabled; therefore, receives a compressed bitstream from the
configuration device. The second Arria II device has the compression feature disabled
and receives uncompressed data.
In a multi-device FPP configuration chain (with a MAX II device or
microprocessor + flash), all Arria II devices in the chain must either enable or disable
the decompression feature. You cannot selectively enable the compression feature for
each device in the chain because of the DATA and DCLK relationship.

This section describes the functionality and implementation of the dedicated remote
system upgrade circuitry. It also defines several concepts related to remote system
upgrades, including factory configuration, application configuration, remote update
mode, and user watchdog timer. Additionally, this section provides design guidelines
for implementing remote system upgrades with the supported configuration
schemes.
System designers sometimes face challenges such as shortened design cycles,
evolving standards, and system deployments in remote locations. Arria II devices
help overcome these challenges with their inherent reprogrammability and dedicated
circuitry to perform remote system upgrades. Remote system upgrades help deliver
feature enhancements and bug fixes without costly recalls, reduce time-to-market,
extend product life, and help to avoid system downtime.
