Developing FFT Applications with Low-Power Microcontrollers

摘要

As low-power microcontrollers (μCs) begin including peripherals that were formerly reserved for larger microprocessors, ASICs, and DSPs, new opportunities for computing complex algorithms at low power levels are becoming possible. This article describes a Fast Fourier Transform (FFT) application (developed using a low-power μC) that includes a single-cycle hardware multiplier.
