feature.
For soft-embedded processor core applications, the controller configures the
programmable logic with the configuration data stored in the flash memory. On
successful configuration, the embedded processor uses the external flash interface to
boot up and run code from the same flash memory, eliminating the need for a
stand-alone flash memory device.
For applications requiring remote system configuration capabilities, a processor or
PLD can use the external flash interface to store an updated configuration image into
a new page in flash memory (the external flash interface coupled with dynamic
configuration). You can obtain new configuration data from a local intelligent host or
through the Internet. Reconfiguring the system with the new page updates the system
configuration.
For more information about implementing remote and local system updates with
enhanced configuration devices, refer to the
Stratix & Stratix GX Devices
Upgrades with Stratix II & Stratix II GX Devices
Currently, EPC4 and EPC16 configuration devices support the external flash interface.
For support of this feature in other enhanced configuration devices, contact Altera
Applications.
You can divide an enhanced configuration device’s flash memory into two categories:
logical (configuration and processor space) and physical (flash data block
boundaries). Configuration space consists of portions of memory used to store
configuration option bits and configuration data. Processor space consists of portions
of memory used to store boot and application code.
