What kind interface does your device use in the field to talk with the outside world?

1). Nios II processor with sufficient memory to run a command processor to accept commands from the outside world

2). Interface to take commands from outside world.

3). Remote Update Controller (Cyclone III) ==> Used to reconfigure the FPGA after the update

4). EPCS Flash Controller ==> This contains a SPI controller you can access directly using a 0x400 base offset and the epcs_commands.h and altera_avalon_spi.h, or via the HAL (altera_avalon_epcs_flash_controller.h)
