I'm looking at this development board from Altera: https://www.altera.com/support/training/university/boards.html#de1-soc
It says it has an ARM processor - this has me confused; does it mean the FPGA is programmed with a microprocessor? In other words, if I program the FPGA with my own Verilog, will it erase the processor and cause the ARM to cease to exist?
If not, why does this board need a microprocessor in the first place? Had one wanted a microprocessor, wouldn't one buy a Raspberry Pi for less, instead?
Thanks for helping me to understand this.
