http://www.dur.ac.uk/cfai/adaptiveoptics/rtc2011/agenda/abstracts/#VV1 Vivek Venugopal (National Solar Observatory): Real-time control for the Advanced Technology Solar Telescope (20 minutes) Real-time processing for Adaptive Optics (AO) systems is challenging as the motion vectors have to be computed to properly actuate the mirrors before the wavefront information has become obsolete. The four meter Advanced Technology Solar Telescope (ATST) will provide unprecedented resolution for solar observation due to its larger aperture. The ATST AO system with 2 kHz frame rate camera, 1750 sub-apertures and 1900 actuators requires massive parallel processing and this increased demand in computational horsepower is far from being manageable by conventional processors. Hardware accelerators such as Field Programmable Gate Array (FPGA) and Graphics Processing Unit (GPU) are better equipped to harness the the parallel processing requirements of such a system. We investigate the implementation of the data processing architecture for Shack-Hartmann correlation and the wavefront reconstruction using FPGAs and GPUs. We benchmark the AO algorithm implemented using FPGAs and GPUs and compare it with the existing legacy FPGA-Digital Signal Processing (DSP) based hardware system used in the 76cm Dunn Solar Telescope(DST).
