FPP Configuration
The FPP configuration in Cyclone IV devices is designed to meet the increasing
demand for faster configuration time. Cyclone IV devices are designed with the
capability of receiving byte-wide configuration data per clock cycle.
You can perform FPP configuration of Cyclone IV devices 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 IV device 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 IV device.
f For more information about the PFL, refer to AN 386: Using the Parallel Flash Loader
with the Quartus II Software.
1 FPP configuration is supported in EP4CGX30 (only for F484 package), EP4CGX50,
EP4CGX75, EP4CGX110, EP4CGX150, and all Cyclone IV E devices.
1 The FPP configuration is not supported in E144 package of Cyclone IV E devices.
1 Cyclone IV devices do not support enhanced configuration devices for FPP
configuration.
FPP Configuration Using an External Host
FPP configuration using an external host provides a fast method to configure
Cyclone IV devices. 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 IV device. You can store configuration data in 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
