Contemporarily, owing to astronomical advancements in the very large scale integration (VLSI) market segments, hardware engineers are now focusing on how to develop their new digital system designs in programmable languages like very high speed integrated circuit hardware description language, (VHDL) and Verilog and consequently target it to Complex programmable logic devices (CPLDs) and Field programmable gate arrays (FPGAs). This paper focuses on using VHDL, to design an application specific integrated circuit (ASIC) liquid dispenser controller system while targeting the device independent architecture (Ultra 3700 CPLD series) for synthesis ,optimization and fitting to realize the design. The ASIC controller has two bin cans to dispense regular and diet drinks. The system dispenses a drink if the user activates a button for that drink and at least one can is available. A refill signal appears when both bins are empty. Activating a reset signal informs the system that the machine has been refilled and the bins are full. The design methodology is presented with other details in the body of this paper.
With the Internet of Everything (IoE) paradigm that gathers almost every object online, huge traffic workload, bandwidth, security, and latency issues remain a concern for IoT users in today’s world. Besides, the scalability requirements found in the current IoT data processing (in the cloud) can hardly be used for applications such as assisted living systems, Big Data analytic solutions, and smart embedded applications. This paper proposes an extended cloud IoT model that optimizes bandwidth while allowing edge devices (Internet-connected objects/devices) to smartly process data without relying on a cloud network. Its integration with a massively scaled spine-leaf (SL) network topology is highlighted. This is contrasted with a legacy multi-tier layered architecture housing network services and routing policies. The perspective offered in this paper explains how low-latency and bandwidth intensive applications can transfer data to the cloud (and then back to the edge application) without impacting QoS performance. Consequently, a spine-leaf Fog computing network (SL-FCN) is presented for reducing latency and network congestion issues in a highly distributed and multilayer virtualized IoT datacenter environment. This approach is cost-effective as it maximizes bandwidth while maintaining redundancy and resiliency against failures in mission critical applications.
National Integration can effectively be realized through a Common Unified Framework (CUF) that will enable the major ethic groups in Nigeria to appreciate communication in their respective languages. This paper developed a language translator application software refered to as NigLT ver1.0, which focus on translating words in the three major Nigerian Languages, (English, Hausa, Igbo Language, and Yoruba Language). This paper argues that the application will assist the citizenry to familiarize with the grammatical structures, meanings and other features of the major Nigerian languages. The application was developed with JAVA programming language and BabelMap Unicode generator, as such making it adaptable to any computer system. In this context, this paper presented the system flowchart and the design methodology This solution will enable end users quickly understand and adapt to its usage.
Electronic-textiles, also known as smart garments, smart clothing, smart textiles, or smart fabrics, are fabrics that enable digital components (including small computers), and electronics to be embedded in them. Smart textiles are fabrics that have been developed with new technologies that provide added value to the wearer. Over the past decade, electronics have been shrinking in size and increasing in functionality. The idea for the most wearable system is to attach technological components to the textile in which transmission lines and connectors are embedded.
