WebHow to convert floating point to fixed point using System Generator in HLS? When using floating-point type in hls, the synthesis report shows that there will be a greater clock delay. Because of the hls tool to convert C / C \+\+ code to hardware RTL, we should consider using fixed-point data types. WebSep 16, 2024 · The 'notes' to go with the above fixed_to_float architecture: -- 16 bit sfixed with 10 bit integer and 6 bit fraction sfixed (9 downto -6) -- the binary point is between index 0 and index -1 -- IEEE-754 single precision floating point. This is a "float" -- in C, and a FLOAT in Fortran.
