최근 3DTV 의 급격한 활성화로 스테레오 영상 콘텐츠 제작이 크게 증가하고 있다. 스테레오 영상은 일반 2D 영상과 달리 깊이(depth)가 존재하므로 자막과 같은 그래픽의 삽입에서 그 깊이를 반드시 고려해야 한다. 또한 시각피로를 줄이기 위해 스테레오 촬영 시 영상의 변이맵(disparity map)을 실시간 관찰할 필요성도 요구되고 있다. 본 논문에서는 최신의 그래픽 하드웨어를 이용하여 듀얼스트림 HD 영상을 실시간으로 스테레오 정합하는 방법을 제안한다.

This paper proposes a hardware of IED for power transformer protection that is well constructed using DSP chip and MPU chip. The performance of the adaptive relaying algorithm, by real-time testing in a prototype of it, has been verified. And test results indicate the proposed relaying of the IED was proven to be faster and more reliable.

ASIC chip design for motor control has been a subject of increasing interest since effective system-on-a-chip design methodology was developed. This paper investigates the design and implementation of ASIC chip for speed control of induction motor using VHDL which is a standarded hardware description language. The presented system is implemented using a simple electronic circuit based on FPGA.

In this paper. we present a new speech recognition system using DSP chip. DSP chip used TMS320c6711 of TI. We designed hardware system including acoustic model, word list and code book in flash memory. The word candidates are recognized based on CV, VCCV, and VC units HMM. This system can be applied to various electric ＆ electronic devices: home automation, robotics etc.

This paper designs a digital correlator for the integrated GPS/GLONASS receiver consisting of DCO, carrier cycle counter, code generator, code phase counter, mixer, epoch counter, accumulator. It is designed using Verilog-HDL(Verilog-Hardware Description Language) and synthesized using EDA(Electronic Design Automation) tools. The performance of the designed digital correlator is verified by the functional simulation and real satellite tracking experiments.

본 논문에서는 차세대 블록 암호 시스템으로 선정되었으며 미연방정부의 표준으로 제정된 RBC(Rijndael Block Cipher) 알고리즘을 하드웨어로 구현하였다. 구현된 블록 암호 시스템은 임베디드 시스템에 적용이 가능하도록 암호화 블록과 복호화 블록을 따로 설계하지 않고 하드웨어를 공유하여 하나의 블록에서 선택에 따라 암호화와 복호화가 모두 이루어질 수 있도록 설계함으로써 하드웨어의 면적을 최소화하였다.

A VPN is widely used in a communications environment which access is controlled to permit peer connections only within a defined community of interest. It is constructed through some form of partitioning of a common underlying communication medium, where this underlying communications medium provides services to the network on a non-exclusive basis. In this paper, we have analyzed a variety of architecture to implement Giga bps VPN system. The proposed architecture will satisfy the needs of clients who adopt Giga bps VPN system in the various environments.

In this paper, the light screen sensing system is introduced and testified to detect small grains such as seeds or electronic chips of uneven sized. Two modules composed of transmitter-receiver sensor array and microprocessor-based sensor signal processing system are developed to realize the proposed system. Experimental results showed that the sensing signal was relatively clear and its counting performance was very stable.
