This paper addresses the I/O latency issue within Xen-ARM. Although Xen-ARM's split driver presents reliable driver isolation, it requires additional inter-VM scheduling. Consequently, the credit scheduler within Xen-ARM results in unsatisfactory I/O latency for real-time guest OS. This paper analyzes the I/O latency in Xen-ARM's interrupt path, and(More)
Market basket analysis is very important to everyday's business decision, because it seeks to find relationships between purchased items. Undoubtedly, these techniques can extract customer's purchase rules by discovering what items they are buying frequently and together.

In this paper, we describe in detail the new event driven architecture for the sensor framework to be used in Tizen. Tizen is an open source, standards-based software platform supported by leading mobile operators, device manufacturers, and silicon suppliers for multiple device categories such as smartphones, tablets, netbooks, in-vehicle infotainment(More)
SUMMARY In this paper, we address latency issue in Xen-ARM virtual machines. Despite the advantages of virtualization in mobile systems, the current Xen-ARM is difficult to apply to mobile devices because it has unpredictable I/O latency. This paper analyzes the latency of incoming packet handling in Xen-ARM, and presents how virtualization affects the(More)
