ECC Description
Enable Error Detection and Status Reporting
  • Enable this option to apply ECC feature for Nios® V processor internal RAM blocks.
  • ECC features detect up to 2-bits errors and react based on the following behavior:
    • If it is a correctable single bit error and Enable Single Bit Correction is turned off, the processor continues to operate after correcting the error in the processor pipeline. However, the correction is not reflected in the source memories.
    • If it is a correctable single bit error and Enable Single Bit Correction is turned on, the processor continues to operate after correcting the error in the processor pipeline and the source memories.
    • If it is an uncorrectable error, the processor halts its operation.
Enable Single Bit Correction Enable single bit correction on embedded memory blocks in the core.
