Triplicated Subsystem Performance and Resource Utilization - 1.0 English - PG268

MicroBlaze Triple Modular Redundancy (TMR) Subsystem LogiCORE IP Product Guide (PG268)

The following table provides approximate performance and resource utilization for typical TMR subsystems, and a comparison with the corresponding single-string subsystem in parentheses. The results were obtained with the IP Characterization and fMAX Margin System Methodology described in the MicroBlaze Processor Reference Guide (UG984). The resource use of the triplicated sub-systems can be less that three times the single-string, mostly because the designs have debug enabled, which is not triplicated.

See Benchmarks for information on how to recreate the designs.
