Together with a new advent of embedded processor developed to support specific application area and it evolution, a new research of software development to support the embedded processor and its commercial challenge has been revitalized. Retargetability is typically achieved by providing target machine information, ADL, as input. The ADLs are used to specify processor and memory architectures and generate software toolkit including compiler, simulator, assembler, profiler, and debugger. The EXPRESSION ADL follows a mixed level approach-it can capture both the structure and behavior supporting a natural specification of the programmable architectures consisting of processor cores, coprocessors, and memories. And it was originally designed to capture processor/memory architectures and generate software toolkit to enable compiler-in-the-loop exploration of SoC architecture. In this paper, we designed the class-based ADL based on the EXPRESSION ADL to promote the write-ability, extensibility and verified the validation of grammar. For this works, we defined 6 core classes and generated the EXPRESSION's compiler and simulator through the MIPS R4000 description.

As the use of various IoT devices increases, the importance of IoT platforms is also rising. Recently, artificial intelligence technology is being combined with IoT devices, and research applying a neuromorphic architecture to IoT devices with low power is also increasing. In this paper, an application scenario is proposed based on NA-IDE (Neuromorphic Architecture-based autonomous IoT application integrated development environment) with IoT devices and FPGA devices in a GUI format. The proposed scenario connects a camera module to an IoT device, collects MNIST dataset images online, recognizes the collected images through a neuromorphic board, and displays the recognition results through a device module connected to other IoT devices. If the neuromorphic architecture is applied to many IoT devices and used for various application services, the autonomous IoT application integrated development environment based on the neuromorphic architecture is expected to emerge as a core technology leading the 4th industrial revolution.

To reduce time to market for converged services, the service provider needs to combine external services and internal processes together, and IT architecture for converged services has to support it. Service Oriented Architecture (SOA) enables the development of a converged service by combining external services and internal processes effectively. However, it is difficult for the existing SOA methods to support the evolution of a converged service, even though the service which consists of the converged service changes over time. In this paper, we argue that a method for profile-based dynamic service binding is required to support evolution of converged services. In order to identify requirements for the proposed method, a business scenario with a smart athletic equipment is given. We then present the concept and architecture of the method for profile-based dynamic service binding to meet the identified requirements. We also demonstrate a prototype implementation for evaluating the proposed method.

The ROK military has established the MND-AF (Ministry of National Defense- Architecture Framework) and is applying it when developing architecture for Enterprise (MND), Segment (component) and Solution (weapons and force support system). The AMM (Architecture Meta model) of the MND-AF supports the establishment of interoperability by systematizing the architecture information structure defined by the Architecture artifact, describing the relationship between data and also by liking reference models and Information technology standard, common components, and MND-Meta data. which are interoperability standards. However, the MND-AMM has insufficient linkage with the standards, which places constraints on applying interoperability standards when developing Solution architecture. This study suggests a logical data model (OV-7c) from the MND-Meta-data-based Architecture meta model that will enhance the application of MND meta data managed by the MND interoperability standard when developing Solution architecture.

Up to the present, most of the previous works, related to the alignment of organizations, have been focused on the alignment between business and information technology. Also these works have been done with single element, e.g., view rather than with overall elements such as view, scope, and perspective for enterprise-wide integrated alignment. Meanwhile, an enterprise architecture is a blueprint that represents the structure of components of organizations and their interrelationships. Nowadays, many organizations attempt to make enterprise-wide alignment of business and information technology based on enterprise architecture. Unfortunately, the enterprise-wide alignment is still in a stage of not only conceptual level but also abstract level. Hence, this paper proposes a structured enterprise-wide alignment model to overcome the limitations of existing alignment models. We survey the existing works and propose the conceptual, the logical, and the physical models for enterprise-wide alignment which includes 3-dimensional elements such view, scope, and perspective based on enterprise architecture. Finally, we have shown that the proposed model is better than existing ones through comparing the characteristics of models.

The current technological revolution pushes forward the innovation in the library information systems. This study proposes functional requirements and an architectural reference model of Semantic Library, recognized as a prototype of next-generation library information systems, that is a seamless convergence of the library information systems and the Internet technologies. Semantic Library can realize semantic interoperability and integration based on ontology and metadata, and also renovate information services for users with openness, sharing, participation and collaboration. Semantic Library will be effectively implemented by means of service-oriented architecture and the logical structure of FRBR. In this study, a reference model of Semantic Library consisting of 6 horizontal layers and 3 vertical elements is presented as a next-generation model of library information systems.
