  • In this paper, design of small microprocessor unit is implemented using research purpose VHDL and CAD tools by top-down design method. For this, original basic MPU and its pipelining architectures are suggested. Once, design target, instruction sets, architecture are decided, the operation is confirmed by C language simulation, and then the operation is confirmed by checking internal register contents for given inputs in the case of VHDL simulation. Then, design layouts are made by full/semi-custom design methods by research CAD tools and related simulation is implemented. The feasibility of suggested pipelined structure for performance improvement is confirmed by simulation, and related problems and future research directions are discussed. In conclusion, the MPU design methodology is set up and the design change of architecture is possible by this paper.

  • This paper describes the design of a network interface controller (NIC) chip which is to be used to support a novel adaptive virtual cut-through routing method for parallel compute systems with direct (i.e., point-to-point) interconnection networks. The NIC chip is designed to provide the interface between a processing node constructed from commercially available microprocessors and another custom-designed router chip, which in turn performs the actual routing of packets to their respective destinations. The NIC, designed using a semi-full-custom VLSi design technique outperform traditional wormhole routing with a minimal amount of hardware overhead. The NIC design has been fully simulated and laid out using a 0.8$\mu\textrm{m}$ CMOS process.

  • A semicustom VLSI design fo digital filters used in TDM/FDM transmultiplexer is described. A filter bank composed of only all-pass digital filter sections are implemented with the polyphase network. The use of all-pass filters as basic building blocks is shown to provide a trans-multiplexer structure that has low computational requirements, low quantization noise, and high modularity. The silicon compiler system is used to reduce the design time and to increase the credibility of designed filters. As a prototype, 1st and 2nd order all pass filter are designed, using CMOS N-well double metal technology. The chip sizes of first order filter and the second order filter are 2652 x 533\ulcorner\ulcorner 5334x4300\ulcorner\ulcorner respectively.

  • In this paper, we designed simultaneous 2-axis control system using commercialized custom ICs for positioning and interpolation that is very compact and high reliable. This system is primarily designed for NC system, we verified it is more complete than the other hardware & software based system in its function, control accuracy and cost. Also, this system can be expanded for multi-axis control, it can be applied to the control of more complicated mechanism such as articulated robot.

  • Mourning & funeral ritual means a various kinds of ritual procedures which begins at the time of death, buried and created a graveyard, a manner of wearing funeral garment being mourning the death, finally go back to everyday life. Our mourning & funeral custom was burial at first time. After going through the era of the Three kingdoms, The unified Shilla and Korea dynasty, cremation method has been prevailed. However, based on Chu-tzu celebration in Chosun dynasty, the burial custom has been widely spread again. Nowadays, due to effective land utilization issue, excessive cost for burial and the change of thinking for cremation, the cremation is recognized as remedy of righteous funeral system. At this point, a shroud following existing burial custom burdens considerably for quality, price, size and design of it. Accordingly, it needs anew style of shroud corresponding to cremation system. As an alternative, the shroud is required simplification and standardization ; Firstly, in size, a shroud should be larger than plain clothes and differentiated in small, medium and large. Secondly, the material of a shroud would be white cotton, which can keep from pollution during burning time. Thirdly, it unifies the item. In case of man, 바지(把特, those are trousers), 저고리(赤古里, Korean-style jacket) and Durumagi(周衣, Korean topcoat). In case of woman, 치마(赤 , those are skirt), 저고리(赤古里, Koran-style jacket) and Durumagi(周衣, Korean topcoat).

  • In this paper, I will propose a Custom-made Suit Production System. The system does not only help the customers to edit and measure their size by creating the landmarks in the 2D human body images which is taken from the camera, but it also visualizes the virtual cloth by using the landmarks and the modeling data of the virtual cloth. In this system is a new technology for the digital and the automation which is not handmade way of using Custom-made Suit industry. It will be generally useful in the various contents of the clothing industry.

  • The choice of suitable hip implant is one of important factors in the total hip arthroplasty (THA). In clinical view point, an improper adaptation of hip implant might induce abnormal stress distribution to the bone, which can shorten the lifespan of replaced hip implant. Currently, interest in the custom-designed hip implants has increased as studies reveal the significance of geometric shape of patient's femur in modeling and designing the implants. In this study, we have developed custom-designed hip implant models with various sizes, and analyzed the stress distribution in the bone and bone cement using the Finite Element Method. It was found that minimizing the gap between implant stem and femoral cavity is crucial to minimize the stress concentration in the bone.

  • This paper presents a design of an optimized implantable biotelemetry system and the fabrication of custom CMOS LSI for implementing this system. The internal circuits of this system are fabricated on a single silicon chip with a size of $4{\times}5mm^2$. This LSI is designed and fabricated not only to get as small size and low power dissipation as possible, but also to have multiple function. Its main functions are to select one of implanted sensors and to accomplish ON - OFF power switching of an implanted battery by receiving appropriate Command signals and control signals fran external circuits. The internal system which was assembled on a bread-board using fabricated LSI chip is confirmed to work as designed. The total power dissipation of this interal system was $10.12{\mu}W$.

  • The mouth guard is a device with elasticity to be installed in the oral cavity. It has a function to reduce the trauma in the oral cavity and to protect the teeth and surrounding tissues from trauma. The purpose of mouth guard is to prevent trauma and concussion. It is mandatory to wear a mouthguard in sports where there is a lot of contact and the possibility of trauma or concussion in the mouth area is high. The mouse guard is divided into a stock type, a mouth formed type, and a custom made type according to the manufacturing method. The custom made type is made on the individual dentition model and has excellent retention because of its excellent fit. Also, the effect of trauma prevention is excellent. It is possible to design and adjust by the dentist and reduce the complaint the athlete has about the mouthguard. In this article, the process of making a dentist-customized mouthguard was described.
