Mobifetch: An Execution-time Prefetching Technique to Expedite Application Launch in Mobile Devices

초록

This paper presents a novel prefetching technique to reduce application launch time for mobile devices. The proposed method traces disk access accurately during an application launch and prefetches them in efficient way at its subsequent launches. The key idea is to parallelize the use of processor and flash disk while exploiting multi-core and internal parallelism on flash disk. The proposed prefetcher implemented on a mobile Meego platform has achieved a 28.1% reduction of application launch time with 6 popular applications.
