TI DM8168 cycle measurement in DSP optimization

1330hayacool7102

Hi friends,
   I use DVRRDK_03.00_
   And we post something in DSP side and try to measure the performance by calculating the cycle difference.
   After tracing the code, we just found two APIs "Utils_getCurTimeInUsec" and "Utils_getCurTimeInMsec" .
   Does any one know how could I do if I want to measure the cycle difference?

Use Timestamp_get64() to get the DSP ticks. Subtract with an earlier value to get cycle difference. Utils_getCurTimeInUsec() / Utils_getCurTimeInMsec() use this API to get ticks and convert to real time based on frequency
