SPECTRAVEL - SPECTRometer on carAVEL

Digital spectrometer generator is designed in Chisel and it contains:

  • Single-path Delay Feedback Fast Fourier Transform (SDF-FFT) accelerator
  • Logarithm-Magnitude circuitry
  • Spectral Accumulator
  • Built-In Self-Test (BIST) consisting of:
    • Numerically Controlled Oscillator (NCO), preceeded by
    • Piecewise Linear Waveform Generator (PLWG)
  • A lot of mux- & spliter-like test structures together with WB2AXI bridge, UART, etc.

This is just a single instance which was produced by a Chisel generator.
