High performance sparse Fast Fourier Transform using OpenACC
The Sparse Fast Fourier Transform (sFFT) is a recent algorithm developed by Hassanieh et al. at MIT for Discrete Fourier Transforms on signals with a sparse frequency domain. A reference implementation of the algorithm exists and proves that the sFFT can be faster than modern FFT libraries for …

Energy efficient reconfigurable SRAM using data-dependency
… applications: the coefficient SRAMs in a sparse Fast Fourier Transform (sFFT) implementation, the Support Vector Machine (SVM) weights SRAM in an objection detection system, and the Motion Estimation (ME) reference pixel SRAM in a video coding system, respectively.
