Abstract:

FFT is one of the basic building blocks in many applications such as sensors, radars, communication, and other real-time signal processing systems. Especially, for real-time spectral monitoring and analysis, FFT is critical and is used both in the channelizer and filtering as well as obtaining the spectrum of the signal. For these systems, ``run-time configurable'' FFT is what makes the system real-time and is one of the most crucial pieces of the design. When examining the literature on configurable real-time FFT implementations (i.e., FPGA-based), it seen that the degree of configurability is less than what is desired. In this thesis, a highly configurable FFT architecture that does not compromise area and throughput is proposed. The configurable parameters of this design are the number of FFT points (up to 64K), forward versus inverse mode, output order (natural or bit-reversed), and the number of streams (up to 4). The proposed FFT architecture (HC-FFT) is designed using a parallel and pipelined radix-2 Multipath Delay Commutator (MDC) FFT structure. HC-FFT was implemented on a Xilinx Kintex XCKU115 FPGA and was verified against Xilinx FFT (v9.1), which is a widely used FFT IP core. Besides its high degree of configurability, HC-FFT is quite efficient and offers a very high throughput of 81 Gbps with a moderate area.
