    Hi Shaoyu,

    DMIPS stands for Dhrystone MIPS (Million instructions per second).  Dhrystone is an open source benchmark, recommend internet search on "what are DMIPS" or "what is Dhrystone" for further details.

    The dhrystone binary is included in PSDK Linux, in the filesystem at ./filesystem/usr/bin/dhrystone.

    For QNX DMIPS measurements, the dhrystone open source package would need to be rebuilt for QNX, and/or QNX would need to be contacted for benchmark details.   

    With any benchmarks, please be aware, system settings, system activity, compiler settings, and code under test will impact measured results.

    Closing this thread as it is a duplicate of ongoing threads.

    Regards,
