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.
