The data processor that performs the waverront 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.In this paper

on the basis of decomposition of wavefront reconstruction algorithn in which the concurrency is embed ded

a pipeline multiple SIMD（PMSTMD）parallel processing architecture is propsed.The hardware simulation experiment showe that the processor based on the PMSIMD architecture is capable of processing video images of 128×128pixels at 850 frames per second and the time delay is less than 1/4 period.
