Is it really fast enough?

Hi, I'm new with NiosII.

Is the NiosII performance comparable with the other 32-bit MCU?

I see when you build a project the IDE creates a bulk of software,

sort of interface with the hardware. Does it overload the CPU with too many functions calls?

Thanx.

    You can't, directly, compare a discrete processor solution versus a softcore processor in FPGA (like Nios II).

    Yes, Nios II is not likely to beat a desktop processor, cycle for cycle, but it's possible for a Nios II based system to outperform a desktop system....for certain applications. This can happen with RTL-based hardware acceleration (C2H, etc.) or DSP-based acceleration, both of which are possible in Nios II (in FPGA) systems.

    Your job will be to determine if a Nios II system can compete with whatever discrete processor system you have in mind.

    once I try to send a number of datas to PIO .then I find that in the modelsim wave time spent on sending data is too long.clock frequence is 50 mhz ,send a data to the PIO need about hundreds of microsecends. Is it too slow?
