This system is obtained when enabling fault tolerance in MicroBlaze, without doing any other configuration.
The system is suitable when area constraints are high, and there is no need for testing of the ECC function, or analysis of error frequency and location. No ECC registers are implemented. Single bit errors are corrected by the ECC logic before being passed to MicroBlaze. Uncorrectable errors set an error signal, which generates an exception in MicroBlaze.
