Release Date
2023.2 English

The below features have been added to the library in this release.

  • DDS / Mixer

The DDS/ Mixer library element now has extended type support. It now supports cfloat and cint32 for TT_DATA when configured as a mixer. When configured as a DDS, cfloat is now supported for TT_DATA. Additionally, the DDS/Mixer now supports Super Sample Rate operation for higher throughput.

  • FFT/iFFT

FFT point size support has been extended to 65536. Performance has been improved approximately 10% for cases using PARALLEL_POWER>1 which were previously supported.

  • FIR Filters

All FIR library elements now support streaming interfaces as well as window interfaces. The single rate asymmetric FIR variant now support Super Sample Rate operation for higher throughput. The FIR resampler library element has been added which performs fractional decimation. This supersedes the existing FIR interpolate fractional library unit. All FIR variants now support a larger maximum value for FIR_LEN, up to 8k depending on variant, data/coefficient type and API choice.
