  • The addressing mode for data is performed by the software in yon Neumann-concept(SISD) computer a priori without hardware design of an address counter for operands. Therefore, in the addressing mode for the vector the corresponding variables as much as the number of the elements should be specified and used also in the software method. This is because not for operand but only for an instructions, quasi PC(program counter) is designed in hardware physically. A vector has a characteristic of a structural dimension. In this paper we propose to design a hardware unit physically external to the CPU for addressing only the elements of a vector unit with the structure and dimension. Because of the high speed performance for a vector processing it should be designed in the SIMD pipeline mechanics. The proposed mechanics is evaluated through a simulation. Our result shows $12\%$ to $30\%$ performance enhancement over CRAY architecture under the same hardware consideration(processing unit).

  • The lighting industry has become the bigger and more systemized using the semiconductor LED with each control R(Red), G(Green), B(Blue). The communication standard DMX512(ANSI E1.11) protocol of it basically needs the address which can be distinguished between the lighting terminals. The conventional method has to give the address of the lighting any methods like dip switch, EEROM and PROM. Then the lighting terminal can receive RGB data from DMX512 communication. According to electrical characteristics DMX512 protocol has to the splitter every 32 lighting terminals. If 512 lightings is all connected, maximum 16 splitters are needed. This paper is solved above weakness in DMX512 protocol using serial connection all lighting terminals. Also I developed the intelligent lighting terminal with auto-addressing. This was solved the inconvenience of the address assignment and the usage of the splitter. The developed products is applied and selled the semiconductor lighting terminals using ON-OFF control, dimming control, sequential control and rainbow control.

  • Various approaches were undertaken by major PDP makers in order to improve the luminous efficacy of the plasma discharge cells. There have been many reports that state that using a high Xe content PDP is one of the most promising key technologies available to improve the luminous efficacy. In the case of the higher Xe content panel, the higher address and sustain voltage were needed to drive the panel under the same reset condition. In this study, a variety of Xe content panels were investigated in order to examine wall voltage transfer behaviors. The transferred wall voltage status after addressing discharge at the same driving condition was analyzed by comparing Vt close curve of high and low Xe content panels. Through this analysis of Vt close curve difference, the driving waveform of a high Xe panel was quantitatively adjusted Under the same address voltage condition, results showed that the amount of the transferred wall voltage and Vt close curve after addressing discharge was matched for the first sustain discharge. Taking these results into consideration, we conclude that the driving waveform for different Xe content panels could be designed for the desired addressing discharge condition and the wall voltage state of the cell could be quantitatively controlled and measured through these approaches.

  • Organic field effect transistors are excellent candidates for addressing and local amplification elements for large area electronics because they can easily be processed at low temperatures on essentially arbitrary substrates. We present the use of these devices in an active matrix photodetector and as a buffer for a strain sensor.
