FIR filters have been categorized into classes and placed in a distinct namespace scope: xf::dsp::aie::fir, to prevent name collision in the global scope. Namespace aliasing can be utilized to shorten instantiations:
namespace dsplib = xf::dsp::aie;
Additionally, each FIR filter has been placed in its unique FIR type namespace. The available FIR filter classes and the corresponding graph entry point are listed below:
| Function | Namespace and class name |
|---|---|
| Single rate, asymmetrical | dsplib::fir::sr_asym::fir_sr_asym_graph |
| Single rate, symmetrical | dsplib::fir::sr_sym::fir_sr_sym_graph |
| Interpolation asymmetrical | dsplib::fir::interpolate_asym::fir_interpolate_asym_graph |
| Decimation, half-band | dsplib::fir::decimate_hb::fir_decimate_hb_graph |
| Interpolation, half-band | dsplib::fir::interpolate_hb::fir_interpolate_hb_graph |
| Decimation, asymmetric | dsplib::fir::decimate_asym::fir_decimate_asym_graph |
| Interpolation or decimation, fractional, asymmetric | dsplib::fir::resampler::fir_resampler_graph |
| Decimation, symmetric | dsplib::fir::decimate_sym::fir_decimate_sym_graph |
