High speed wavefront processor for adaptive optics system - pipeline multiple SIMD architecture

The data processor that performs the wavefront reconstruction is one of the three components of a discrete adaptive optics (AO) system. It must satisfy the processing needs in AO system in real time. On the basis of decomposition of wavefront reconstruction algorithm in which the concurrency is embedded, a pipeline multiple SIMD (PMSTMD) parallel processing architecture is proposed. The hardware simulation experiment shows that the processor based on the PMSIMD architecture is capable of processing video images of 128×128 pixels at 850 frames per second and the time delay is less than 1/4 frame period.
