Multiple NIOS V Implementation

Hi,

I was looking at the NIOS V Processor Reference Manual. I could not find the max instantiations you can implement on a FPGA. I see many designs online of Nios II Multiprocessors. Can I make the assumption that it is the same as the Nios II and you can implement multiple instantiations of NIOS V on the same FPGA, as long as the hardware logic space (alm), memory, etc can support the design.

Lastly, is there any examples online for this?

I see examples like

https://www.intel.com/content/www/us/en/support/programmable/support-resources/design-examples/horizontal/exm-multi-nios2-hardware.html

and

https://www.intel.com/content/www/us/en/design-example/714531/cyclone-v-creating-multiprocessor-nios-ii-systems-design-example.html

and

Thanks!

    Hi,

    Unfortunately, the official support for Nios V to use Mutex HAL API is not yet supported.

    You may implement them at your own accord and we may not be able to support further if you encounter issue.

    With this, do you have any further questions?

    Again, we apologies giving you this bad news.

    Hi,
    GeMRTOS (https://gemrtos.com) supports multiple Nios V/m processors. GeMRTOS is a multiprocessor RTOS that also supports Nios 2/e/f.
    The GeMRTOS Platform Designer IP component may be downloaded from https://github.com/G-RTOS/GeMRTOS.
    niosv-download issue avoids downloading the .elf file (most of the times) when more than 2 processors are instanciated. This issue was not fixed in Quartus Prime Standard Edition version 22.1 (https://www.intel.com/content/www/us/en/support/programmable/articles/000089679.html).
    Regards.
