floating point library

Discussion in 'VHDL' started by salman sheikh, Nov 20, 2003.

  1. Hello,

    Has anybody had any experience with the IEEE floating point library
    specifically those at:

    http://www.eda.org/fphdl/

    Has anybody tried to synthesize them and how does one convert from fixed
    point to floating point?
    Thanks in advance.

    Not until I clicked on that link.

    Well, the link above says that only this package
    is synthesizable:

    http://www.eda.org/fphdl/vhdl/fphdl_base_pkg.vhd
    http://www.eda.org/fphdl/vhdl/fphdl_base_pkg_body.vhd

    The package contains conversion functions fp_to_<type>.
