abstract = "Future space telescopes such as the Habitable Worlds Observatory (HWO) will require fast execution of high-order wavefront sensing and control (HOWFSC) algorithms to achieve the necessary contrast to image an Earth-like exoplanet around a Sun-like star. In this work, we port over the computationally-dominant algorithms for HOWFSC onto two current-generation space processors: the NXP T1040 and the LS1046A RDB. We utilize these processors to control a high-fidelity optical model of the telescope to demonstrate, for the first time, the ability to dig a dark hole in a processor-in-the-loop test with flight-like hardware. We additionally time individual HOWFSC routines like optical modeling and variants of Electric Field Conjugation (EFC) to estimate the HOWFSC algorithm latency induced by current generation flight-like hardware.",
