Nios II Processor or
The Quartus II software provides the flexibility to include the remote system upgrade
interface between the Stratix IV device logic array and the dedicated circuitry,
generate configuration files for production, and allows remote programming of the
system configuration memory.
The ALTREMOTE_UPDATE megafunction is the implementation option in the
Quartus II software that you use for the interface between the remote system upgrade
circuitry and the device logic array interface. Using the megafunction block instead of
creating your own logic saves design time and offers more efficient logic synthesis
and device implementation.
The ALTREMOTE_UPDATE megafunction provides a memory-like interface to the
remote system upgrade circuitry and handles the shift register read and write
protocol in the Stratix IV device logic. This implementation is suitable for designs that
implement the factory configuration functions using a Nios II processor or user logic
in the device.
