Design of sloth real time kernel on a hybrid system

The picky needs raised in the embedded market lead to the growth of real-time operating systems (RTOS), which differ from the general-purpose operating systems (GPOS) by applying strict timing and providing predictable execution of tasks. Some features of a real-time application, such as human interaction and some data transfers to other components are not time-critical. As the general-purpose operating system requires access to the data gathered by the real-time operating system, these two should be consolidated on the same platform form a hybrid system. This proposal examines how the existing Sloth approach of interrupt-driven scheduling can apply to a hybrid system running both a real-time and the Linux kernel simultaneously on the unchanged hardware. This entails a make another study of existing approaches towards a real-time capable Linux and the design of a communication channel between the real-time core and processes running in Linux kernel. The evaluation of the resulting Slothful Linux is supposed to show the advantages of the Sloth approach in a hybrid system compared to both the standalone Sloth and another real-time conservatory for Linux.
