Table: TMR Subsystem Performance and Resource Utilization
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 f
MAX
Margin System Methodology described in the
MicroBlaze Processor Reference Guide
(UG984)
[Ref 5]
. 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.
