Support for arbitrary precision data types in NIOS II Eclipse

[Krus83]

I would like to use arbitrary precision data types in NIOS II Eclipse to run the HLS-components that use ac_int and ac_fixed. Is there any way to add support for this in NIOS II Eclipse?

Quartus/HLS/NIOS version 18.1

Hi @Krus83,

Thank you for posting in Intel community forum and hope this message find you well.
If I understand request correctly, you are seeking something similar with data type such as ac_int and ac_fixed in HLS.
For that maybe I would suggest that you can look into this custom instruction for nios ii which implement math floating point here.
Please do let us know if that help clarify your doubts.
