Enabling compression reduces the amount of configuration data that is
transmitted to the Stratix III device, which also reduces configuration
time. On average, compression reduces configuration time, depending on
the design.
Programming Serial Configuration Devices
Serial configuration devices are non-volatile, flash-memory-based
devices. You can program these devices in-system using the
USB-Blaster™ or ByteBlaster™ II download cable. Alternatively, you can
program them using the Altera programming unit (APU), supported
third-party programmers, or a microprocessor with the SRunner
software driver.
You can perform in-system programming of serial configuration devices
via the conventional AS programming interface or JTAG interface
solution.
As serial configuration devices do not support the JTAG interface, the
conventional method to program them is via the AS programming
interface. The configuration data used to program serial configuration
devices is downloaded via programming hardware.
During in-system programming, the download cable disables device
access to the AS interface by driving the nCE pin high. Stratix III devices
are also held in reset by a low level on nCONFIG. After programming is
complete, the download cable releases nCE and nCONFIG, allowing the
pull-down and pull-up resistors to drive GND and V

configuration device.
Altera has developed Serial FlashLoader (SFL); an in-system
programming solution for serial configuration devices using the JTAG
interface. This solution requires the Stratix III device to be a bridge
between the JTAG interface and the serial configuration device.
