The below features have been added to the library in this release.
- DDS Mixer LUT - new library element
| Function | Namespace and class name |
|---|---|
| DDS Mixer LUT | xf::dsp::aie::mixer::dds_mixer::dds_mixer_lut_graph |
This element adds a second implementation of a DDS/Mixer that provides higher SFDR figures than the existing DDS/Mixer solution.
Supports both AIE and AIE-ML devices (EA).
- DDS Mixer
The usage of Input Window Size parameter (TP_INPUT_WINDOW_VSIZE) has been changed in the DDS and DDS Mixer LUT elements to be consistent with other library elements. TP_INPUT_WINDOW_VSIZE describes the number of samples processed by the graph in a single iteration run.
- FFT Window
FFT Window now supports AIE-ML devices (EA), in addition to AIE devices.
- FFT/iFFT
FFT/iFFT now supports AIE-ML devices (EA), in addition to AIE devices.
- FIR Filters
Single Rate FIRs now support AIE-ML devices (EA) with the 16-bit data types and 16-bit coeff types which are listed below:
| Data Type | |||
| Int16 | Cint16 | ||
| Coefficient type | Int16 | Supported | Supported |
| Cint16 | note 1 | Supported | |
|
|||
All FIR library elements now support AIE devices with 16-bit data types and 32-bit coefficients which are listed below:
| Data Type | |||
| Int16 | Cint16 | ||
| Coefficient type | Int32 | Supported | Supported |
| Cint32 | note 1 | Supported | |

FIR Resampler now supports Super Sample Rate operation for higher throughput, through polyphase decomposition.
