Fixed point support in NIOS II

Hi, Im trying to run an HLS-component from NIOS II. The component uses fixed point data type. Is there anyway to add support for arbitrary precision fixed point data type in NIOS II?

// datatype used in component

typedef ac_fixed<16,2,false> test;

    Hi @Krus83,

    Thank you for posting in Intel community forum and hope all is well.
    Per my understanding you can do so by custom instruction in Nios ii.
    Details explanation can be found here, hope that clarify.
