Abstract
Our aim is to investigate the possibility to control the throughput (IPC rate) of a thread running on a multithreaded microprocessor by a closed feedback loop. We showed in previous experimental studies the practability of this approach. In this paper we discuss the control theory approach from a mathematical point of view. We develop a formal model of a general purpose multi-threaded microprocessor enhanced with a closed feedback controller and use control theory methods to investigate properties like stability and settling time.
