10.4. Uniprocessor Systems

In this section, we will present the basics of uniprocessor scheduling, which are the prerequisites for understanding multiprocessor scheduling. We will describe how a uniprocessor system may be modeled using SystemC [446] and, in particular, compare two widely used on-line schedulers for uniprocessor scheduling; RMS and EDF.

Our basic system model consists of three types of components: task, RTOS, and link, with the link providing communication between the tasks and the RTOS. In this section, we present the scheduling service of the RTOS model, and in Sections 10.4.4 and 10.4.5, we extend the RTOS service model to include synchronization and resource allocation. Tasks can send the messages (ready and finished) to the ...
