Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: SYSBIOS, MMWAVE-SDK

We want to calculate the running time of the algorithm and use the Cycleprofiler_getTimeStamp () function.

Please tell us if the following is correct?

<1> for DSP :

Cycleprofiler_getTimeStamp => 1/ DSP_clock_speed=> step= 1/600MHz

<2> for ARM R4F

Cycleprofiler_getTimeStamp => 1/ARM_clock_speed=> step= 1/200MHz

<3> Also tell us where to find this function information : "Pmu_getCount(0)"

Thanks!

Hi Jason,

Both <1> and <2> are correct on clock speed, please see the Technical Reference Manual section on Clock Domain for more information.

<3> The Pmu_getCount(0) is a function native to SysBios that is used in the mmWave-SDK. For the function please look in your bios folder at the following location, C:\ti\bios_6_73_01_01\packages\ti\sysbios\family\arm\v7a

Let me know if you have more questions.

Regards,
