Real-Time Android: Deterministic Ease of Use.

In: Proceedings of Embedded Linux Conference Europe, Nov 5 - 7, 2012


The rapid ascent of Android to one of the most influential platforms for mobile devices and tablets shows that the platform meets the preferences of end-users and developers with consistent usability and a convenient development environment targeted at the needs of the many instead of a specialised few. Being based on the Linux kernel, it inherits the rich and mature feature set which made Linux the number one embedded operating system in just a few years. The Android stack, however, only uses and provides a small subset of those features. Real-time capabilities, which enabled Linux for a much broader embedded audience, were not considered in the Android design. By introducing a real-time capable Android appliance, we add a crucial Linux building block combining the benefits of both realms. Besides presenting the software architecture, we discuss our efforts in augmenting the Android stack with RT capabilites in a minimally invasive way, provide effort measurements, and present a performance evaluation based on a prototype implemented using a Motorola Xoom tablet featuring our architecture extensions.
