Bus scheduling implementation on the cell processor
Real-time computing is the study of hardware and software systems that are subject to a “real-time constraint” - i.e., strict deadline guarantees. With uncontrollable cache and front side bus, in the modern computer architectures, the estimation of a tight bound, worst case execution time (WCET) is …
