When multiple Cyclone III devices are cascaded, you can selectively
enable the compression feature for each device in the chain.
depicts a chain of two Cyclone III devices. The first Cyclone III device has
compression enabled and receives a compressed bitstream from the
configuration device. The second Cyclone III device has the compression
feature disabled and receives uncompressed data.
You can generate programming files for this setup from the Convert
Programming Files dialog box (File menu) in the Quartus II software.
Remote System Upgrade
Cyclone III devices support remote update mode when using the remote
system upgrade feature. You can enable or disable remote update mode
with an option setting in the Quartus II software. Remote system
upgrades help deliver feature enhancements and bug fixes without costly
recalls, reduce time-to-market, and extend product life.
Cyclone III devices support remote update in the AS and AP
configuration schemes. You can implement remote update in conjunction
with real-time decompression of configuration data if you need to save
configuration memory space in the serial configuration device with AS
configuration.
