The TMR Manager is responsible for handling the TMR subsystem state, including fault detection and error recovery. The core is triplicated in each of the sub-blocks in the TMR subsystem, and provides majority voting of its internal state. The TMR Inject core provides functional fault injection by changing selected MicroBlaze instructions, which provides the possibility to verify that the TMR subsystem error detection and fault recovery logic is working properly. For more details about TMR Manager and Inject IPs please refer PG268[1].
