Timing the duration of functions NIOS II

Hello,

I was wondering how I can time the duration it takes the NIOS II processor to perform a certain series of functions (for example a DMA transfer).

Or where I can find some good information regarding this matter?

I'm using NIOS II IDE.

Thanks in advance.

    Ah thanks, exactly what I needed :). Somehow google didn't give me that .pdf and I somehow I missed that their was something as a performance counter described in the Embedded Peripherals IP .pdf.

    To make this thread more useful for someone else: in the following map (on your PC) you can find the details on how the (easy to use) performance counter works: ...\altera\10\quartus\sopc_builder\documents\performance_counter_readme.html

    But the performance counter does confirm my bad feelings though, namely that my system is terrible slow.:mad: See this thread:
