Description: # IEEE754 Floating-Point ALU, in nmigen
        
        This project implements a pipelined IEEE754 floating-point ALU that
        supports FP16, FP32 and FP64.  It is a general-purpose unit that
        may be used in any project (not limited to one specific processor).
        
        Developed under a Grant from NLnet (http://nlnet.nl), more information
        may be found at http://libre-soc.org
        
        # Requirements
        
        * nmigen
        * libresoc-nmutil
        * yosys (latest git repository, required by nmigen)
        * sfpy (running unit tests).  provides python bindings to berkeley softfloat-3
        
        # Building sfpy
        
        The standard sfpy will not work without being modified to the type of
        IEEE754 FP emulation being tested.  This FPU is emulating RISC-V, and
        there is some weirdness in x86 IEEE754 implementations when it comes
        to FP16 non-canonical NaNs.
        
        The following modifications are required to the sfpy berkeley-softfloat-3
        submodule:
        
            cd /path/to/sfpy/berkeley-softfloat-3
            git apply /path/to/ieee754fpu/berkeley-softfloat.patch
        
        The following modifications are required to the sfpy SoftPosit Makefile:
        
            cd /path/to/sfpy/SoftPosit
            git apply /path/to/ieee754fpu/SoftPosit.patch
