Paper Abstract

For CCD wavefront sensor pixel input and processing the Adoptics software in use at the Mt. Wilson 100-inch Hooker telescope utilizes hand-crafted assembly code to maximize use of the Texas Instruments C40 DSP processor's bandwidth. For flexibility the software is built around a conceptual framework that allows compact implementation of wavefront sensor-specific operations as well as adaptability to different CCD architectures. Designed for use in multi-DSP systems, such as those used at Mt. Wilson, the software framework will support many different DSP network topologies and facilitates distributing pixel-processing operations across the network.
