Hardware Implementation of a Pipelined 64-Point FFT/IFFT Processor
Mathematical Background and Design Goals
The Fast Fourier Transform (FFT) is an efficient algorithm to compute the Discrete Fourier Transform (DFT). For a sequence $x(n)$ of length $N$, the DFT is defined as:
Module Interface Specification
The top-level entity, named fft_top, features a standard streaming interface. The input and output data ...

Rounding and Saturation Truncation for Fixed-Point Data in Verilog
In digital signal processing implementations, data quantization and bit truncation are common operations. This article covers two critical techniques: rounding to preserve precision during truncation, and saturation handling when results exceed representable ranges.
Data Format Notation
Fixed-point data formats follow the mQn convention where m ...
