1.4.2. Flexible Peripheral Set and Address Map

A flexible peripheral set is one of the most notable differences between Nios® II processor systems and fixed microcontrollers. Because the Nios® II processor is implemented in programmable logic, you can easily build made-to-order Nios® II processor systems with the exact peripheral set required for the target applications.

Intel FPGA provides software constructs to access memory and peripherals generically, independently of address location. Therefore, the flexible peripheral set and address map does not affect application developers.

There are two broad classes of peripherals: standard peripherals and custom peripherals.
