Maximum Frequencies
The maximum frequency of a triplicated MicroBlaze subsystem itself is generally not significantly reduced. However, the majority-voted outputs from the subsystem impose an additional logic level, which might affect the overall frequency.
When using the internal SEM option with the TMR SEM core, the frequency is limited to the SEM sub-core maximum frequency. To avoid this limitation, the external SEM option can be used, to allow clocking the SEM with a slower clock.
Latency
There is no additional latency imposed by triplicating the MicroBlaze subsystem. The majority voting on the outputs is combinatorial.
Throughput
There is no difference in throughput or computational performance imposed by triplicating the MicroBlaze subsystem. A triplicated subsystem has exactly the same performance as a single-string subsystem.
Power
The power requirements of a triplicated subsystem is at least three times the equivalent single string subsystem, and can approach four times due to the additional power consumed by the TMR cores.
