摘要：

This paper presents a parallelization method utilizing dead time to implement higher precision control systems on multi-core processors. It is known that dead time is hard to handle with in control systems. In our method, the dead time is explicitly represented as delay blocks of models such as Simulink. Then, these delay blocks are distributed to the overall systems with equivalent transformation, so that the system can be simulated or executed in pipeline parallel. With a spring-mass-damper model, our technique accomplishes x3.4 performance acceleration on an ideal four-core simulation, and x1.8 on cycle-accurate simulator of a four-core embedded processor as a threaded application on a real time operating system.
