Cyclone V SoC - Time execution function - Cycle count

Hi everybody,

I'm new on SoC architecture and I need to measure cycle count about some function using NEON instruction.

My goal is to measure optmization code compared to an other architecture.

In Texas Instrument or Analog Devices case, I can put MACRO on code. Theses MACRO allows an hardware cycle counter in order to calculate function cycle time.

Example from Analog Devices:

• #include <cycle_count.h>

• START_CYCLE_COUNT(S)

• STOP_CYCLE_COUNT(T,S)

Example from TI:

• #include <c6x.h>

• start_time = _itoll(TSCH, TSCL);

• end_time = _itoll(TSCH, TSCL);)

• cyclecount= end_time - start_time;

• or directly with Code Composer Studio.

ARM Compiler, DS-5 on eclipse or an other tools allow that?

Thank a lot,

Remy
