Floating point not working in Nios V

Hi,

I will further duplicate and validate from my side to see whether it's a bug. Will keep you updated if I have any findings.

Thank you.

Hi,

Have you added the hardware floating point component on platform designer to carry out the calculation? If not, the Floating Point Hardware component is under Embedded Processors on the Component Library tab.

We do have NIOS II Custom Instruction guide which should be similar to the application of NIOS V for your reference here: https://www.intel.com/content/www/us/en/docs/programmable/683242/current/nios-ii-floating-point-hardware-2-component.html

Thank you.

Can you share the steps to add the library?

Hi,

As Nios V is still at an early stage of release, we do not have the exact documentation of steps for NIOS V newlib set up. But here is adding the NIOS II new lib which should work the same for your reference : https://www.intel.com/content/www/us/en/docs/programmable/683242/current/nios-ii-fph2-and-the-newlib-library.html

Thank you.

Thank you.

I am still not sure how to add the library, Can you guide me by steps?

Hi Chris,

I just got some news back from the engineering team. Unfortunately support for hardware Floating Point Unit (FPU) is not currently available in Nios V therefore floating point cannot be performed. This feature is expected to be released in future Quartus version.

Thank you so much for posting on Intel forum and I shall set this case to close-pending in the next few days.

Kelly
