Abstract:
The real-time processing requirements for the four meter Advanced Technology Solar Telescope extended source high order adaptive optics system will be approximately 15 times that of the Dunn Solar Telescope AO systems on which the ATST AO system is based. The ATST AO, with its approximately 1232 subapertures, will use massively
parallel processing and is based on Analog Devices TigerSHARC DSPs as the central processing units. We will discuss the requirements for processing and data handling and the architecture of the correlating Shack-Hartmannn and reconstructor processing unit and present the results of bench-mark testing of the DSP hardware that was
selected for the ATST AO system.
