Formats chapters in volume 2 of the Configuration Handbook.
Configuration Features
Stratix IV devices offer design security, decompression, and remote system upgrade
features. Design security using configuration bitstream encryption is available in
Stratix IV devices, which protects your designs. Stratix IV devices can receive a
compressed configuration bitstream and decompress this data in real-time, reducing
storage requirements and configuration time. You can make real-time system
upgrades from remote locations of your Stratix IV designs with the remote system
upgrade feature.
Table 10–3 lists which configuration features you can use in each configuration
scheme.

If your system already contains a common flash interface (CFI) flash memory, you can
use it for Stratix IV device configuration storage as well. The MAX II parallel flash
loader (PFL) feature in MAX II devices provides an efficient method to program CFI
flash memory devices through the JTAG interface and provides the logic to control
configuration from the flash memory device to the Stratix IV device. Both PS and FPP
configuration modes are supported using this PFL feature.
f For more information about PFL, refer to Parallel Flash Loader Megafunction User Guide.
