FPP Configuration Using a Microprocessor
In this configuration scheme, a microprocessor can control the transfer of
configuration data from a storage device, such as flash memory, to the
target Stratix III device.

microprocessor as an external host. Refer to this section for all
configuration and timing information.
In the fast AS configuration scheme, Stratix III devices are configured
using a serial configuration device. These configuration devices are
low-cost devices with non-volatile memory that feature a simple four-pin
interface and a small form factor. These features make serial
configuration devices an ideal low-cost configuration solution.
For more information on serial configuration devices, refer to the
Configuration Devices Data Sheet
Serial configuration devices provide a serial interface to access
configuration data. During device configuration, Stratix III devices read
configuration data via the serial interface, decompress data if necessary,
and configure their SRAM cells. This scheme is referred to as the AS
configuration scheme because the Stratix III device controls the
configuration interface. This scheme contrasts with the PS configuration
scheme, where the configuration device controls the interface.
