Critical infrastructures require precise and swift response to a local disturbance before it would spread and accumulate. To meet the demand on response time, we propose an intelligent controller with cache design. The controller stores previous decisions and rates them based on a comprehensive evaluation. With those ratings, the controller can intelligently choose the decision leading to the optimum result. Meanwhile, cache is used to further reduce the access time to the stored decisions. Speedups up to 4.7X over the former centralized infrastructures are achieved based on our hardware design and simulation.
