Abstract

Our aim is to investigate if it is possible to control the throughput (IPC rate) of a thread running on a multithreaded Java processor by a closed feedback loop. We implemented a Proportional/Integral/Differential (PID) controller in the processor simulator of the Komodo microcontroller developed at the universities of Karlsruhe and Augsburg to simulate the PID controller as an additional hardware module. It uses the GP (Guaranteed Percentage) scheduling to control the thread. Evaluations show that the aimed IPC rate of a thread is achieved by the controller thus improving the real-time capabilities of the Java processor.
