This chapter describes the functionality and implementation of the dedicated remote
system upgrade circuitry. It also defines several concepts related to remote system
upgrade, including factory configuration, application configuration, remote update
mode, and user watchdog timer. Additionally, this chapter 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. Stratix
help overcome these challenges with their inherent re-programmability 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,
and extend product life.
Stratix III devices feature dedicated remote system upgrade circuitry. Soft logic (either
the Nios
download a new configuration image from a remote location, store it in configuration
memory, and direct the dedicated remote system upgrade circuitry to initiate 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. This dedicated
remote system upgrade circuitry is unique to the Stratix series and helps to avoid
system downtime.
Remote system upgrade is supported in fast active serial (FAS) Stratix III
configuration schemes. You can also implement remote system upgrade in
conjunction with advanced Stratix III 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 dedicated remote system upgrade circuitry in Stratix III devices manage remote
configuration and provides error detection, recovery, and status information. User
logic or a Nios II processor implemented in the Stratix III device logic array provides
access to the remote configuration data source and an interface to the system's
configuration memory.
Stratix III devices have remote system upgrade processes that involves the following
steps:
1. A Nios II processor (or user logic) implemented in the Stratix III device logic array
2. The Nios II processor (or user logic) stores this new configuration data in
receives new configuration data from a remote location. The connection to the
remote source uses a communication protocol such as the transmission control
protocol/Internet protocol (TCP/IP), peripheral component interconnect (PCI),
user datagram protocol (UDP), universal asynchronous receiver/transmitter
(UART), or a proprietary interface.
