  • 인터넷의 사용이 증가, 네트워크 기술이 발달하면서 컴퓨터 및 하드웨어 장비는 고속화 대용량화, 소형화 추세로 가고 있고, 기존에 외부 인터페이스와의 데이터 송수신 또한 병렬 포트를 이용한 통신이 많았으나, 외부 장비의 소형화와 고속화 그리고 휴대화가 요구되면서 차츰 직렬 포트를 이용하여 적은 전송라인을 이용한 외부 장비와의 인터페이스가 요구 되게 되었다. 본 논문에서는 내부 모듈간의 인터페이스와 외부 장치와의 데이터 송/수신이 가능한 UART 인터페이스 모듈을 하드웨어 설계언어인 VHDL 언어를 이용하여 설계하였으며, FPGA 칩인 Xilinx(Spartan II) 데스트 보드에 다운로드하여 시뮬레이션 하였다. 또한 양방향성 공통 버스로의 인터페이스 회로 설계와 다른 클럭으로 동작하는 시스템과의 비동기 회로의 동작 메커니즘을 쉽게 설계하였고, 비동기 통신 기능에 있어서 실제로 사용이 가능하도록 설계하였다.

  • 유도무기는 점검장비와 MIL-STD-1553B 통신 시 많은 양의 데이터를 처리하고, 전달 받은 데이터에 대해 정확성과 빠른 응답성을 요구하기 때문에 점검장비에서 데이터를 실시간으로 처리하고 판단하는 것이 매우 중요하다. 따라서 본 논문에서는 이러한 문제를 해결하기 위해 기존에 개발된 실시간 이식 커널을 이용하여 미들웨어에서 MIL-STD-1553B 통신에 요구되는 주기적인 통신의 마감시간을 보장하도록 설계 및 구현하였다.

  • In this paper, we propose context-aware system for semiconductor equipment that acquires information from multiple sensors in indoor environment. This proposed system acquires information from acceleration, pressure, temperature and gas sensors then the acquired information send to server. The data transmitted to server generates an alarm via context-aware algorithm of unit event and multi event. From that result, high-quality real-time monitoring is possible because of the reduced unnecessary alarms, and the efficient management is possible because the surrounding information is recognized at once.

  • This paper aims to find influencing factors for firms to adopt network equipments which based on Advanced Telecom Computing Architecture (ATCA). ATCA suggests a standardized specification for telecom equipments design. This new paradigm of developing network equipment provides benefits for network equipment manufacturers by reducing development time for new equipments with lower CapEx and OpEx. It also deliver oportunities for telecom services providers to exploit or test new services by replacing or upgrading part of total system with modular based network equipments. The research model basically depends on various researches based on Rogers' Innovation and Diffusion theory and it is verified through an empirical study for ninety-one domestic forms. Binary logistic regression was conducted to find the relationship between purchase intention and factors affecting new technology adoption. As a result, two factors such as scalability and cost/benefit effectiveness of the new system were statistically significant. Cluster analysis followed with those two variables. This helps TEMs (Telecom Equipments Manufacturers) get some implications on timing and target customers for diffusing the ATCA based technologies in the market.
