(IPFlex) today announced that they have jointly developed two-dimensional
fast Fourier transform accelerator (FFT accelerator)(1) using DAPDNA-2(2)
dynamically reconfigurable processor(3), shortening phase retrieval process by
an order of magnitude. It spends mere 87 seconds for a 1000-repetition phase
retrieval for 1024x1024 pixel image reconstruction, while conventional
CPU-based system spends more than 20 minutes to do the same. Until now, researchers had to either wait until entire sample
data was collected, or spend much time analyzing the intermediate data, before
deciding to proceed with the test. The
laboratory used IPFlex's DAPDNA-EB4 board with two DAPDNA-2s and implemented
HIO algorithm. DAPDNA-2 can change
its hardware configuration to provide the optimal circuitry for an application
on demand. With its DAPDNA series of dynamically
reconfigurable processors and design tools, IPFlex provides a platform to
shorten development cycle and enable unprecedented flexibility in hardware.jp/

Development Background
Currently, image reconstruction of amorphous samples using SPring-8 is
conducted in a three sequential steps: collection of coherent x-ray scattering
data, measurement of scattering distribution with two-dimensional detectors,
and realization of actual image with mathematical phase retrieval.
