Development Trends of Digital Infrastructure

The goal of this chapter is to analyze the main trends in the development of information communication technology (ICT) infrastructure and to discuss ICT strategies for decision-making in the 21st century. The chapter begins with a discussion of the development of the internet and its impact on civilization and human society. Next, the chapter considers the development of smartphone applications as well as other technologies used for personal communication. After this, developments in hardware and machine software platforms are considered. The chapter concludes by analyzing three trends: developments in computer architecture, developments in computer design, and developments in IT design.

Decision Support System in a Memristor-Based Mobile CIM Architecture Applied on Big Data Computation and Storage

Data computation and storage are essential parts of developing big data applications. The memristor device technology could remove the speed and energy efficiency bottleneck in the existing data processing. The present experimental work investigates the decision support system in a new architecture, computation-in-memory (CIM) architecture, which can be utilized to store and process big data in the same physical location at a faster rate. The decision support system is used for data computation and storage, with the aims of helping memory units read, write, and erase data and supporting their decisions under big data communication ambiguities. Data communication is realized within the crossbar by the support of peripheral controller blocks. The feasibility of the CIM architecture, adaptive read, write, and erase methods, and memory accuracy were investigated. The integrated circuit emphasis (SPICE) simulation results show that the proposed CIM architecture has the potential of improving the computing efficiency, energy consumption, and performance area by at least two orders of magnitude. CIM architecture may be used to mitigate big data processing limits caused by the conventional computer architecture and complementary metal-oxide-semiconductor (CMOS) transistor process technologies.

Mathematics for Future Computing and Communications

For 80 years, mathematics has driven fundamental innovation in computing and communications. This timely book provides a panorama of some recent ideas in mathematics and how they will drive continued innovation in computing, communications and AI in the coming years. It provides a unique insight into how the new techniques that are being developed can be used to provide theoretical foundations for technological progress, just as mathematics was used in earlier times by Turing, von Neumann, Shannon and others. Edited by leading researchers in the field, chapters cover the application of new mathematics in computer architecture, software verification, quantum computing, compressed sensing, networking, Bayesian inference, machine learning, reinforcement learning and many other areas.

Design and Implementation of English Listening Teaching Based on a Wireless Communication Microprocessor and Virtual Environment

This paper presents an in-depth analysis and research on teaching English listening through a wireless communication microprocessor combined with a virtual environment and designs and implements an English listening teaching experiment. Based on an in-depth understanding of wireless communication algorithms, this thesis extends the instruction set based on the general-purpose compact instruction set computer architecture (RISC) for common operations in wireless communication algorithms, adding new instructions such as multiplication and addition and bit inversion. The microprocessor has an increase in the number of execution clocks for wireless algorithm processing. The processor is extended with an interrupt interface to facilitate information interaction between the processor and the external environment to achieve coordinated work between the processor and the accelerator and to further enhance the speed of digital signal processing through the introduction of the accelerator. An overview and comparison of the status of domestic and foreign research are presented in the vein of VR teaching and the overall development of English teaching. Then, the problems and hypotheses to be explored in this study are presented, and several types of research methods used to explore the solutions to the problems are introduced. The results of the two classroom formats were compared, and specific performance data were obtained. The analysis of the results showed that the students in the VR scenario teaching group made greater progress in vocabulary judgments, complementary dialogues, and Chinese to English translation, with a 43% merit rate and a 100% pass rate in English for the whole group. The real-life scenarios created through VR technology greatly increased students’ interest in learning and significantly improved the effectiveness of classroom teaching. The development trend of education informatization is towards virtualization and intelligence, and the application of VR to the process of education teaching is of great significance to promote the modernization of secondary education informatization.
