  • In semiconductor IP reuse, precise understanding of semiconductor IP interfaces is essential for integrated chip design. However, in general, these interfaces are described in the original designer's description style. Furthermore, their description method are not unified, so it is very difficult for the chip integration designer to understand them. This paper proposes a standardized description method of semiconductor IP interfaces. It consists of 9 items such as IP information, description level, model provision, data type, interface information, port information, signal information, protocol information, and source file. The proposed method helps the chip integration designer to understand semiconductor IP interfaces and to integrate them into a single chip.

  • Although it is not necessary to have much mathematical knowledge in Major Courses of Animal Resources curriculums in agricultural high school, the function of mathematics class has a much effect on Major Courses. Therefore, we extracted the mathematics contents included in Major Courses of Animal Resources curriculums in agricultural high school, and also evaluated students' understanding according to the description method in textbooks of Major Courses. Furthermore, we analyzed students' preference about the description method in textbooks related to the Major Courses. As a result, it turns out that the level of mathematics contents of Animal Resources major curriculums does not break bounds of middle school level. Furthermore, many students are not able to solve the middle school level of problems. It is also shown that the most preferred description method in textbooks of Animal Resources major curriculums is the sentence-equation mixed type. In this study, we propose to reconstruct the mathematics contents with basic knowledge needed to complete the Major Courses in order that students can complete them more easily, and furthermore, to choose the description method in textbooks of Major Courses as sentence-equation mixed type and detailed explanation about terms should be included into the bargain.

  • As an attempt to investigate the use of common verbs by a small group of Korean college students at the advanced level, the present study describes the students' speech production data collected from picture description tasks. The primary focus of the data description was how the students used high-frequency verbs in describing everyday activities. Out of total 442 units, 149 verbs were erroneously used. All erroneous utterances were classified into four categories according to their characteristics. The most prominent error type was overgeneralization due to incomplete knowledge of lexical items. Results showed that verbs used in everyday life were not easy even for the advanced level students. Although in some cases, L1 influence was discerned, the students' problems are more fundamental. In particular, the data revealed lack of knowledge of collocational possibilities and restrictions, and confusion about semantic boundaries between verbs which have similar semantic areas. The findings suggest that teaching at the advanced level should take contrastive approaches intralingually as well as interlingually to the high-frequency verbs.

  • The verification portion of SoC design consumes about 70% of total design effort. To reduce the verification effort and time, it is necessary and desirable to raise the level of SoC design verifications level from the signal or cycle level to the transaction. This paper describes a generation method of transaction monitor modules that monitor interface signals, logging the transaction executions, and report transaction errors. The input of the generation method is a transaction-oriented interface protocol description.

  • Bibliographical Description for Revolutionary Historical Archives is created to describe records at the item level. It defines descriptive elements, punctuations, formats and methods. Descriptive elements are composed of 20 elements, each of which is either mandatory or optional. Mandatory elements are: repositories codes, documents codes, dates, creators, title, classification codes, and subject vocabularies. Abstracts were previously included in card cataloging and are removed in the computerized system. New elements, such as "uncontrolled vocabularies," "name of places," "personal names," "organizational structures" and "meetings," are added to allow keyword search. Considering that subject vocabulary searches are the most important in computerized systems, however, Guidelines for the Subject Indexing for Revolutionary Historical Archives as well as Subject Headings, as a result from the Guidelines, are created. The most extraordinary features in Chinese archival description are said to be the Guidelines for the Classification Indexing for Revolutionary Historical Archives and Materials as well as the Classification Scheme, both of which are created to allow subject search of records content. It is because Chinese practice of records management distinguishes the classification for arrangement from that for retrieval. Chinese archival description is, therefore, composed of bibliographic description rules, subject headings, and the classification scheme for retrieval.

  • It is possible but not efficient to model and simulate asynchronous microprocessors with the existing HDLs(HARDware Description Languages) such as VHDL or Verilog. The reason it that the description becomes too complex. and also the simulation time becomes too long to explore the design space. Therefore it is necessary to establish a methodology and develop a tool for modeling the handshake protocol of asynchronous microprocessors very easily and simulating it very fast. Under this objective an efficient CAD(Computer Aided Design) tool SLEDS(System Level Event-Driven Simulator) was developed which can evaluate performance of a processor through modeling with a simple description an simulating with event driven engine in the system level. The ultimate goal in the tool SLEDS is to fin the optimal conditions for a system to produce high performance by balancing the delay of each module in the system. Besides SLEDS aims at verifying the design through comparing the expected results with the actual ones by performing the defined behavior.

  • A new High level hardware Description Language, ASPHODEL(Algorithm Synthesis Pascal Hardware for Optimal Design and Efficient Language), and its algorithm compiler for high level synthesis are described in this paper. The new HDL, appropriated to the description of algorithmic level and lower, models VLSI circuits as an abstracted block which is consisted of input/output ports and hierachical processors to control VLSI complexities with efficiency. Also, in order to improve the descriptive power, popular Pascal programming language is modified to build ASPHODEL syntax rules. ASPHODEL algorithm compiler generates an intermediate form through lexical and syntax analysis from ASPHODEL source codes. To show the validation of presented language and its compiler, those are applied to practical design examples.
