Soft-core Stream Processing on FPGA: An FFT Case Study
Published in 2013 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), pp. 2756–2760, 2013
This paper introduces a novel soft-core implementation of the Fast Fourier Transform (FFT) on Xilinx Virtex FPGA technology. By employing a streaming processing architecture, the authors demonstrate that it is possible to achieve architectures offering 1.1 GSamples/s throughput and up to 19 times speed-up against the Xilinx Radix-2 FFT dedicated circuit with comparable cost.
Key contributions include:
Soft-Core Implementation: Development of a soft-core FFT implementation on FPGA, providing flexibility and reconfigurability.
Streaming Architecture: Utilization of a streaming processing architecture to enhance throughput and efficiency.
Performance Evaluation: Achievement of 1.1 GSamples/s throughput and up to 19 times speed-up over the Xilinx Radix-2 FFT dedicated circuit.
