The following features have been added to the library in this release.
- AIE-MLv2 - New device support (EA) is being added to DSPLIB.
Early Access (EA) support for AIE-MLv2 device is being added to the following library elements:
- Bitonic Sort
- DDS Mixer LUT
- DFT
- FFT
- FFT Window
- Filters
- TDM FIR
- Hadamard
- Kronecker
- Outer Tensor
- Matrix Mult
- Matrix Vector
- Sample Delay
- Config Helper - Console Interface script for configuring DSPLIB IPs.
Config Helper works in conjunction with the DSPLIB metadata for helping users to build legal configurations and generate resulting graphs for DSPLIB AIE-IPs.
- Bitonic Sort - New library element.
| Function | Namespace and class name |
|---|---|
| Bitonic Sort | xf::dsp::aie::bitonic_sort |
This element adds an implementation of the bitonic sorting algorithm.
Supports AIE, AIE-ML and AIE-MLv2 (EA) devices.
- FFT - New features and optimizations.
In this release a new parameter has been added to the FFT: TT_OUT_DATA. This parameter allows the output data type to differ from the input data type. e.g. to allow TT_DATA (input) to be cint16 with TT_OUT_DATA to be cint32. Also, various optimizations have been implemented to reduce the memory resource used by some configurations of the FFT.
- FFT 2D - New library element.
| Function | Namespace and class name |
|---|---|
| fft_ifft_2d_graph | xf::dsp::aie::fft::two_d::fft_ifft_2d_graph |
This configurable design library element implements a 2D FFT/IFFT function, decomposing FFT algorithm into AIE Tiles and MEM Tiles.
Supports AIE-ML devices.
- FIR TDM - New features and optimizations.
In this release various optimizations have been implemented to optimize throughput and/or reduce memory footprint. In addition, new parameters have been added to the FIR TDM: TT_OUT_DATA and TP_CASC_LEN. These parameters allow:
- the output data type to differ from the input data type. e.g. to allow TT_DATA (input) to be cint16 with TT_OUT_DATA to be cint32.
- FIR workload can be split into multiple kernels connected through the cascade interface, offering increased throughput at the cost of additional resources.
- Function Approximation - New library element.
| Function | Namespace and class name |
|---|---|
| Function Approximation | xf::dsp::aie::func_approx |
This element provides a vectorized linear approximation of a function, f(x), for a given input data, x, using a configured lookup table of slope and offset values that describe the function.
- Mixed Radix FFT - New Features
In this release the dynamic point size has been added to the IP, selected by setting the new parameter TP_DYN_PT_SIZE to 1. This IP now supports cint32 and cfloat for TT_DATA and cint32 for TT_TWIDDLE.
- VSS FFT/IFFT 1CH (AIE + PL) - New library element.
In this release a VSS (Vitis Sub-System) FFT/IFFT has been added to the DSPLIB. This configurable design element implements a single-channel DIT FFT/IFFT, decomposing FFT algorithm into AIE Tiles and PL (programmable logic).
Supports AIE and AIE-ML devices.
