4.1.6. Memory Protection Unit Settings

The Nios II/f core offers a memory protection unit (MPU) to support operating systems and runtime environments that desire memory protection without the overhead of virtual memory management. Turning on Include MPU includes the Nios II MPU in your Nios II hardware system.
Note: The Nios II MPU is optional and mutually exclusive from the Nios II MMU. Nios II systems can include either an MPU or MMU, but cannot include both an MPU and MMU in the same design.

For information about the Nios II MPU, refer to the Programming Model chapter of the Nios II Processor Reference Handbook.
