宋洛雲,全宇衡 弘益大學校 科學技術硏究所 1998 科學技術硏究論文集 Vol.9 No.2
In this paper, a π/4-QPSK modulator, one of the digital modulators, is designed and implemented. The architecture mainly consists of three components; i. e, serial-to-parallel converter, signal mapping block and FIR filter. In FIR filter design, memory blocks are used instead of multiplier to improve speed and to decrease chip area. Here, 11.52kbits memory is used, and pipeline operation is adopted by inserting registers. The designed architecture is simulated by c, VHDL languages and related layout is made by Berkeley CAD tools. In result, the modulator outputs are confirmed to be almost equal, and the signal frequency is found to operate up to 20Mhz.

본 연구에서는 교육용 VHDL 및 관련 CAD 툴을 사용하여 대표적인 디지탈 시스템, 즉, 마이크로프로세서, 디지탈 필터의 설계를 수행한다. VHDL 모의해석의 경우, 행위/구조 모델링을 사용하여 모의해석하였으며, 주어진 입력에 대하여 정상적으로 동작하였으며, 이를 교육용 CAD 툴에 의해 풀커스텀/세미커스텀 설계방식에 의해 레이아웃을 수행하였을때 유사한 결과를 얻을 수가 있었다. 아울러 관련 문제점 및 향후 연구 방향에 관해 논한다. In this work. typical digital systems designs, e.g., microprocessor unit, digital filter, are implemented using education-purpose VHDL and CAD tools. In VHDL simulation, the simulation results using behavioral/structural modeling are performed normally for given inputs and similar results are obtained when layouts are made by full-custom/semi-custom design methods using educational CAD tools. Further, related problems and future research directions are discussed.

金洛龜 영남철학회 1984 哲學論叢 Vol.1 No.-
Die Pflicht ist bekanntlich der Hauptbegriff in Kantischen Ethik. In "Kritik der praktischen Vernunft" lobpreist Kant die Erhabenheit und Grossheit von der Pflicht. In der Pflicht liegt eine Notigung des Wollens und Handelns. Sie ist eine moralische Notwendigkeit. Und sie ist der kategorischen Imperativ, welchem jeder Mensch unbedingt absolut gehorsam sein muss. Besonders die Gesetzgebung der Vernunft selbst ist die Grundlage der Pflicht. Indessen Kant sagt in "Grundlegung zur Metaphysik der Sitten": "Es ist uberall nichts in der Welt, ja uberhaupt auch ausser derselben zu denken moglich, was ohne Einschrankung fur gut konnte gehalten werden, als allein ein guter Willen." Der gute Wille selbst, der Wille zur Pflicht um dieser selbst willen, ist absolut gut und wertvoll. Der Begriff der Pflicht entalt den Begriff eines guten Willens. So in dieser Abhandlung versuchte ich, den Begriff der Pflicht und ihres Prinzip in der Kantischen Ethik ausfuhrlich zu diskurieren.

In this work, 2D FIR DF is designed and simulated by C. VHDL languages. Designed two-dimensional digital filter mainly consists of one-dimensional digital filter and line memory. Once digital filter coefficients are represented by CSD(Canonical signed Digit) formats, multipliers are realized by hardwired-shifting methods. To speed up the 1D DF block, carry-save adder in each tap and Manchester adder in every 1D DF are adopted. The designed filter is performed up to 30 MHZ and related layouts are now in progress by Berkeley CAD tools.

In this work, the VLSI design framework is made by establishing design methodology with respect to the corresponding design levels. To achieve this, the related design CAD softwares, i.e., critical path calculation, schedulingr by simulated annealing, VHDL works, are developed at each design level. The MPC chip is made by the prepared CAD design environment, and presently the data paths such as Booth multiplier, ALU, are designed.

In this paper, two-dimensional wavelet encoder with efficient architecture for real-time image processing is designed. The architecture consists of parallel filter, input control unit and address control unit, and threee storage module is used to simplify related control units. Further, boundary data unit is made for perfect image decoding and scheduling method is adopted to control restricted hardware efficiently. The designed encoder is simulated by C and VHDL language, where reasonable capability is confirmed.
