The FPP configuration in Cyclone III device family is designed to meet the increasing
demand for faster configuration time. Cyclone III device family is designed with the
capability of receiving byte-wide configuration data per clock cycle.
You can perform the FPP configuration of Cyclone III device family with an intelligent
host, such as a MAX II device or microprocessor with flash memory. If your system
already contains a CFI flash memory, you can use it for the Cyclone III device family
configuration storage as well. The MAX II PFL feature in MAX II devices provides an
efficient method to program CFI flash memory devices through the JTAG interface
and the logic to control configuration from the flash memory device to the Cyclone III
device family. Both PS and FPP configuration schemes are supported using this PFL
feature.
For more information about the PFL, refer to
with the Quartus II
Cyclone III device family does not support enhanced configuration devices for PS or
FPP configurations.
FPP configuration is not supported in the E144 package of Cyclone III devices.
FPP Configuration Using an External Host
The FPP configuration using an external host provides a fast method to configure
Cyclone III device family. In the FPP configuration scheme, you can use an external
host device to control the transfer of configuration data from a storage device, such as
flash memory, to the target Cyclone III device family. You can store configuration data
in either an .rbf, .hex, or .ttf format. When using the external host, a design that
controls the configuration process, such as fetching the data from flash memory and
sending it to the device, must be stored in the external host device.
the configuration interface connections between the Cyclone III device family and an
external device for single-device configuration.
