Hello,
As a person who worked with Xavier for quite a while, dual-core lockstep is supported. Nvidia uses their own CPU cores, not Arm's.
See: https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3231/index.html#page/Tegra%20Linux%20Driver%20Package%20Development%20Guide/mb1_platform_config_xavier.html https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-323... for how to enable it.
> enable_ccplex_lock_step: Boolean; enables or disables CCPLEX dual-core lock step.
- jeffreygoesto 6y agoVery interesting, thank you very much! I know the lockstepped R5s and the dual execution feature of the Carmels (close but no cigar for ISO26262), but not that one. Gonna ask our FAE about it eventually. ;-D
- my123 6y agoNot to get your hopes down... but dual-execution in the Carmels and DCLS for CCPLEX should be references to the same thing. :)
- jeffreygoesto 6y agoAaaah! Ok, so I did not overlook a big feature but knew it under a different name. Thanks for the clarification!
