Virtualization offers significant benefits, such as better isolation and security for mobile systems. However, the limited amount of memory and virtualization’s memory-demanding nature make it challenging to virtualize mobile systems efficiently. In this paper, we utilize morphable resistive memories to design a high-performance mobile system with an extensible memory space. With morphable resistive...
Mobile virtualization provides a secure and reliable mobile ecosystem in many aspects, such as personal privacy, corporate and public security. However, the limited memory resources of mobile systems and virtualization's memory demanding feature post challenges on main memory. Fortunately, non-volatile random access memory(NVRAM) provides opportunities to solve the problem with its attractive features,...
Mobile virtualization introduces extra layers in software stacks, which leads to performance degradation. Especially, each I/O operation has to pass through several software layers to reach the NAND-flash-based storage systems. This paper targets at optimizing I/O for mobile virtualization, since I/O becomes one of major performance bottlenecks that seriously affects the performance of mobile devices...
Mobile virtualization introduces extra layers in software stacks, which leads to performance degradation. Especially, each I/O operation has to pass through several software layers to reach the NAND-flash-based storage systems. Among all the I/O operations, a large percentage is updating metadata. Frequent updating metadata not only degrades overall I/O performance but also severely reduces flash...
