We show resistive switching effects in memristive devices exhibit significant stochasticity. When the switching is dominated by a single filament, the switching time is fully random and shows a broad distribution. However, the switching distribution can be predicted and responds well to controlled changes in the programming conditions. The native stochastic characteristic can be used to generate random...
A two-terminal memristor device is a promising digital memory for its high integration density, substantially lower energy consumption compared to CMOS, and scalability below 10 nm. However, a nanoscale memristor is an inherently stochastic device, and extra energy and latency are required to make a deterministic memory based on memristors. Instead of enforcing deterministic storage, we take advantage...
To trajectory programming, then bring about the high intelligent requirements according to the planned path for trajectory tracking. The static circumstance trajectory programming Based on grid circumstance model has been researched and analyzed. The ant-colony algorithm, which has been analyzed and proved to be effective by the simulation result, has been advanced.
This paper describes how memristors, together with CMOS transistors (CMOS-memristor hybrids), could be used for analog arithmetic within cellular (locally connected, regular) computing arrays, i.e., cellular nanoscale networks (CNN). Elementary analog programming of memristors and copying memristance values are described. Also, we show how memristors could be used for addition, subtraction, multiplication...
We describe a generic exponential model with four parameters for thin-film memristive devices. This model is used to analyze the time dependency of the threshold voltage which defines the transition between non-programming and programming phases of the device. A relationship between timescale of operation and threshold voltage is derived. Furthermore, self-terminating programming is considered using...
Carrying out science at extreme scale is the next generational challenge facing the broad field of scientific research. Cloud computing offers to potential for an increasing number of researchers to have ready access to the large scale compute resources required to tackle new challenges in their field. Unfortunately barriers of complexity remain for researchers untrained in cloud programming. In this...
Embedded systems are becoming more and more popular in current digital era. In order to improve the development efficiency, a framework of Object-Oriented (OO) program on embedded system is designed in this research. UML modeling language is adopted to construct the model of embedded system. By using UML, programmers can understand the system structure easily and improve the system design. This will...
We report studies on nanoscale Si-based memristive devices for memory and neuromorphic applications. The devices are based on ion motion inside an insulating a-Si matrix. Digital devices show excellent performance metrics including scalability, speed, ON/OFF ratio, endurance and retention. High density non-volatile memory arrays based on a crossbar structure have been fabricated and tested. Devices...
With the emergence of service oriented architecture, service orchestration has been an important paradigm of building large-scale distribute systems. The performance of orchestrating services is critical to the entire system. Meanwhile,with the growing complexity the programmability of writing service orchestration program has became a pressing concern. In this paper, we presents a service orchestration...
Sustaining uniformity of software artifacts from phases through software lifecycle is very important for efficient software evolution and maintenance. Most requirement documents were written in ambiguous natural language which is less formal and imprecise. Without proper modeling, the requirement information and knowledge is captured laboriously and informally, thus the following integration with...
Most requirement documents are written in natural languages and represented in less structured and imprecise formats. Including requirement phase. Artifacts created in phases of software life cycle are required to be modeled and integrated, so the traceability, consistency, and completeness can be ensured. Without proper assistance, extracting and integrating artifacts in requirement documents represented...
