Multiple Configuration File for Cyclone IV E

Hallo I am using Cyclone IV E (EP4CE22F17C6) with a slightly customized DE0-NANO board. Currently i am using the JTAG to program the FPGA and its volatile. I know that the board has an EEPROM w...

I'm not sure I see any advantage in using multiple EEPROMs - this just makes your hardware more complicated. There are plenty of EEPROMs/FLASH memory devices big enough to hold lots of FPGA images. However, there's nothing wrong with using multiple devices.

How long to reconfigure? Cyclone IV supports 133MHz using passive serial configuration. For a 720kByte image - about 43ms. You're more likely to be limited by your micro/EEPROM combination.

Cheers,
