Timing the duration of functions NIOS II

Altera_Forum · ‎12-10-2010

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.

Have a look at the performance counter (chapter 34 of this doc (http://www.altera.com/literature/ug/ug_embedded_ip.pdf))

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:
