The Radix-2 Burst I/O architecture uses one Radix-2 butterfly processing engine ( This Figure ). After a frame of data is loaded, the input data stream must halt until the transform calculation is completed. Then, the data can be unloaded. As with the Radix-4 Burst I/O architecture, data can be simultaneously loaded and unloaded when the output samples are in bit reversed order. This solution supports point sizes from 8 to 65536. Both the data memories and phase factor memories can be in either block RAM or distributed RAM (the latter for point sizes less than or equal to 1024).
