(a) 2D FFT performance: DRAM tile-hopping
(b) 2D FFT with EAR performance: PSD versus OPSD
Figure 10: Performance evaluation in terms of frames per second for (a) 2D FFTs with tile-hopping memory pattern. (b) 2D FFTs with edge artifact removal (EAR) using OPSD. The performance evaluation shows the significance of the two optimizations proposed. Both axes are on a log scale.
