1.5.3. ECC Support

Starting in v13.1, the Nios II Processor parameter editor lets you enable ECC protection for the RAMs in the processor core and the instruction cache.

By default, ECC is not enabled on reset. Therefore, software must enable ECC protection. Software can also inject ECC errors into RAM data bits to support testing of the ECC exception handler and event bus.

The Nios II Hardware Abstraction Layer (HAL) is extended to support ECC initialization and exception handling.
