Or what is the factor if not?</P> Mon, 25 Nov 2024 08:09:26 GMT https://community.nxp.com/t5/T-Series/Probability-for-CPU-producing-identical-data-in-lockstep/m-p/2000837#M5084 Xingzi 2024-11-25T08:09:26Z https://community.nxp.com/t5/T-Series/Probability-for-CPU-producing-identical-data-in-lockstep/m-p/2001845#M5085 <P>There are no hardware provisions for that in any T-series or P-series processor and no recommendations for implementing it are available.</P> Tue, 26 Nov 2024 09:32:05 GMT https://community.nxp.com/t5/T-Series/Probability-for-CPU-producing-identical-data-in-lockstep/m-p/2001845#M5085 yipingwang 2024-11-26T09:32:05Z
