DSP

These examples show how to use GAP9 to do various Digital Signal Processing including image and sound. In the autotiler folder you can find examples using directly the Autotiler to generate code:

• MatAdd Autotiler
• MatMul Autotiler
• DotProd Autotiler

In the nntool folder you can find examples using the NNTool to generate code for the Autotiler:

• MelSpectrogram Using NNTool
• Librosa (Log)MelSpectrogram on GAP
• Librosa Mfcc on GAP
• Librosa Stft on GAP
• DFT Using NNTool + Autotiler
• RFFT + IRFFT Using NNTool
• PDM INPUT-OUTPUT + FFT Example

In the benchmarks folder you can find examples using directly the DSP library from the Autotiler without the code generation (manually moving data from the memory hierarchy). This is mostly for testing GAP cycles and power consumption on known DSP benchmarks.

• Complex FFT L1 Benchmark
• RFFT L1 Benchmark
• iRFFT L1 Benchmark
