Location-Based Service (LBS) has become more and more important with the rapid development of mobile internet, it as an information service mainly make use of geographic position of mobile phone to provide accurate services for consumers. LBS involves a mass of longitude-latitude data and mainly involves three problems: Point Query, Range Query, and K-Nearest Neighbors. The object of this paper is...
Memory virtualization plays an important role in system virtualization. However, traditional memory virtualization solutions are usually for those architectures with hardware-managed TLBs, such as x86, ARM and so on. The solutions for architectures with software-managed TLBs are rarely mentioned. This paper presents three different memory virtualization solutions for architectures with software-managed...
The increasing scale and complexity of virtualized data centers pose significant challenges to system management software stacks, which still rely on special-purpose controllers to optimize the operation of cloud infrastructures. Autonomic computing allows complex systems to assume much of their own management, achieving self-configuration, self-optimization, self-healing, and self-protection without...
Mobile application services are growing sharply in China at present. However there is a great lack of human resources in this domain. Therefore, it is of great significance to cultivate people who are good at mobile application service development for social needs. The requirements for human resources in the mobile application services is overlapping, diverse, and practical, thus its curriculum includes...
In Java programs, it needs to use the information of the method type to resolve the virtual method dynamically, which restricts the performance greatly. Currently, the solution is mainly the technique of inline caching, which can be divided into two categories: monomorphic inline caching and polymorphic inline caching. Because of the simple implementation of monomorphic inline caching, it is more...
Applied software, running mode, architecture and security are problems which especially attract the attention from commercial circulation enterprises in construction of Supply-chain Management System. A Supply-chain Management System consisting of SaaS platform, Smart Client and Service-oriented Architecture can maintain cooperation, interaction and smooth operation of work flow, information flow,...
Binary translation is one of the most important approaches for system migration. However, software binary translation systems often suffer from the inefficiency and traditional hardware-software co-designed virtual machines require the unavoidable re-design of the processor architecture. This paper presents a novel hardware-software co-designed method to accelerate the binary translation on an existing...
