Part Number: TDA4VL-Q1

Hello TI,

In C7X processor, we have __TSC for calculating profiling time. What is the equivalent method in R5F Main and R5F MCU cores.

Thanks

hi,

Well, in vision apps, we use GTC timer on all main domain cores. You can use the same.

Hi,

You could refer the API appLogGetTimeInUsec() present in ${PSDKRA}/vision_apps/utils/console_io/src/app_log_rtos.c .
