Abstract
This paper presents ESP to optimize E merging S torage P rimitives with virtualization for flash memory storage systems. We propose two optimization strategies, virtual duplication and mapping prefetching to solve the critical issues in existing emerging storage primitives. The objective is to reduce unnecessary flash memory accesses and keep RAM footprint of address mapping table well under control. We have evaluated ESP on an embedded development platform. Experimental results show that ESP can significantly improve the write/read performance and reduce over 30% of garbage collection operations.
