8.3. Declaring ac_complex Data Types
- Include the ac_complex.h header file in your component in the following manner:
#ifdef __INTELFPGA_COMPILER__ #include "HLS/ac_complex.h" #else #include "ref/ac_complex.h" #endif
- After you include the header file, declare your ac_complex variables according to the data type of your complex number.
The underlying data type can be ac_int, ac_fixed, hls_float, and standard C integer or floating-point data types.
For a list of supported operators and their return types, see "4. Complex Datatype" in Mentor Graphics Algorithmic C (AC) Datatypes, which is available in the following file: <quartus_installdir>/hls/include/ref/ac_datatypes_ref.pdf.
