Recent research on imprecise computation (that is, flexible computation) at the University of Illinois has focused on the development of operating system support for imprecise computations. The scheduling algorithms and imprecise-computation environment resulting from this work enable the use of imprecise computation as a means to provide scheduling flexibility in real-time systems and to enhan...
