摘要：

The increasing demand for real-time embedded applications makes evident the need for end-to-end Quality of Service (QoS) provisioning. In order to achieve the end-to-end QoS, we propose the implementation of the control and management of QoS mechanisms in the operating system scheduler. A new scheduling algorithm, named ER-EDF, is proposed and compared to previous scheduler solutions. This approach was validated through a set of benchmarks and we conclude that ER-EDF adds performance and simplified hard real-time support to real-time embedded applications.
