We investigated the endurance characteristics of a Cu-doped HfO2 selector device in one transistor-one selector (1T1S) structure, which is fully compatible with standard BEOL process. The device exhibits high endurance of 1010 under 10 μΑ compliance current. However, reduced endurance (105) was observed as increasing the compliance up to 100 μΑ. Under the condition of high operation, intrinsic defect...
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...
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,...
1T1R-architecture devices were fabricated by integrating ZrO2 based crossbar structure ReRAM onto a foundry-built MOSFET platform. Multilevel operation was realized by using the current limit of a selected cell transistor in the set process. The current level was determined by the transistor's gate voltage, resulting in the control of electrical resistance of the filamentary conductive paths in the...
We propose a computing technique for efficient parallel simulation of compute-intensive DEVS models on the IBM Cell processor, combining multi-grained parallelism and various optimizations to speed up the event execution. Unlike most existing parallelization strategies, our approach explicitly exploits the massive fine-grained event-level parallelism inherent in the simulation process, while most...
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...
With the development of Web service technology, SOA has so many applications in industries. How to evaluate a domain oriented service becomes an important issue at present. This paper puts forward an extended SOA (exSOA) architecture and a domain expert-based evaluation model for Web service. It evaluates the candidate service by considering the evaluation result from domain expert and the constraint...
