Field UpgradeableSpartan Configuration
Spartan configuration is transferred across USB from host system— Configuration image is contained in device driver— No configuration PROM required
Microcontroller loads Spartan— Reads data from USB ASSP, writes configuration data to
Spartan
Advantages— Spartan configuration updateable by new driver— Field upgrades/bug fixes
