On the Design of Flexible Real-Time Schedulers for Embedded Systems

A major subject in real-time embedded systems is the management of the tasks that compose the system respecting its real-time constraints. This is usually accomplished by the adequate selection of a scheduling policy. This work proposes a design and implementation of real-time schedulers for embedded systems within the context of Application Oriented System Design (AOSD), enabling the development of schedulers where the policy is detached from the scheduling mechanism. The results shows that such implementation could scale from 8 bits microcontrollers, 32 bits architectures, and to specific hardware implemented design.
