Predictive system-level control

Optimising system performance by anticipating the system’s next operational use

Today’s high-tech embedded systems need to provide optimal performance under a wide range of inputs, either from the user or the environment. For example, a state-of-the-art printing system has to handle a large variety of paper types and print jobs. For the internal system design, each input category is represented by a separate operational mode.

During operation, a mode transition may cause a large disruption of the overall system performance. As a result, the transition between operating modes must be carefully managed.

The predictive system-level control method incorporates techniques that anticipate a system’s next operational use. It prepares the system’s transition from one mode to another as soon as a mode-switching event is foreseen. By iterative optimisation of system transitions, a higher overall system performance can be achieved.
