Region-specific cache structures for Android mobile platforms
[Examensarbete på avancerad nivå]
The popularity of Android operating system in mobile platforms, as well as constant development in Android systems as modern mini computers, increase the complexity and the size of the virtual memory. Therefore, the need for studying and categorizing Android memory system becomes essential for design and improvement of the memory organization. In this work, we purpose two modern cache organizations, namely, region cache and drowsy cache to enhance the Android memory performance. These cache designs are based on multiple simulations on gem5 while running Agave Android benchmark suite. We pro le the Android virtual memory to examine which memory regions are accessed the most, and which cache blocks are reused during the run time for dfferent applications. The simulations suggest that many memory regions' hit-rate can be improved by the proposed cache designs in this work.
