[FAQ] TDA2E: How to do profiling in the Vision SDK

Hi,

Use the below API To get current Global time in the units of micro sec's 

Utils_getCurGlobalTimeInUsec() :  This API should be called in the Bios core only (IPU, DSP, EVE, A15(Bios))

OSA_getCurGlobalTimeInUsec() :  This API should be called in the Linux core only (A15(Linux))

Example code for profiling

UInt64 currTime, prevTime, diffTime;

prevTime = Utils_getCurGlobalTimeInUsec();

MyFunc();

currTime = Utils_getCurGlobalTimeInUsec();

diffTime = currTime - prevTime;

Vps_printf("Time taken by Myfunc is %u\n",diffTime );

Thanks
