This thesis proposes an automatic instruction extension system that utilizes retargetable compiler, based on MDL, to design an ASIP optimized for application. The proposed system uses information gathered from the application program to find all possible expandable instruction candidates. Expandable instruction candidates acquire the realization characteristics through hardware library. The system chooses instruction set and optimizes processor structure satisfying constraints on the bases of hardware characteristics and increase in execution speed. To confirm the efficiency of the proposed system, automatic instruction extension system was performed using various benchmark applications. The proposed system acquired optimized instruction set and processor structure, which are expanded from the commercial version of ARM9TDMI. Experimental results show that number of execution cycle has been reduced by 33.5% when compared to conventional version of ARM9TDMI, while area has been slightly increased.

This study examines the relationship between instruction using ICT and the students' moral judgement and academic achievement in ethics course in a middle school, and analyses the difference of learning effects according to gender. For the purpose of this study, the two hypotheses are established. One is that there would be a significant difference in learning effect between ICT instruction groups and teacher-centered instruction groups. The other is that there would be a significant difference in learning effect between male groups and female groups. This study sampled 144 students of four classes from the first graders of a middle school in Taejon. For experimental treatment, this study designed two instructional programs: ICT-using instruction and teacher-centered instruction. ICT-using instruction program was applied to two classes(72 students), and teacher-centered instruction program to the other two classes(72 students). The experimental design of the study was the pretest-posttest control group design. As a result of this study, the ICT-using instruction program influenced positively the students' moral judgement and its improvement. Concerning the degree of academic achievement, there was no significant difference between the ICT-using groups and the teacher-centered groups. The sex distinction among ICT-using groups does not make any significant difference in the moral judgement and academic achievement.

Korea is a record powerhouse nation with the largest number of Memory of the World in the Asia-Pacific; however, active utilization of archives for future generations has been lacking. Therefore, this study sought to enhance interest in archives and utilize them directly in school lessons. The Korean National Debt Redemption Movement's archives, which were selected as a Memory of the World, were used in the school lessons, and based on them, a library collaborative instruction design was developed. A library collaborative instruction is a collaboration between the high school Korean history subject and the library information literacy instruction, designed in three sessions. Through the literature research-based design, a library collaborative instruction plan, teaching and learning plan, and activity sheets were derived. Implementing this designed library collaborative instruction is expected to stimulate interest in the Memory of the World, linking curriculum and archives at schools and significantly expanding the users of the archives into teachers and students.

This study intended to identify the differences of pre-service elementary school teachers' perceptions on instructional design between face-to-face and online instruction. Lesson plans for face-to-face and online instruction were analyzed by 84 participants who were seniors at C university of education. Results of content analysis indicate that 'Providing Learning Guidance' domain is the biggest domain in terms of the frequency gap between face-to-face and online instruction. Frequency differences by domains between face-to-face and online instruction were found to be significant as a result of Chi-square test. Frequency differences by instructional elements in the 'Providing Learning Guidance' domain between face-to-face and online instruction were found to be statistically significant as well. In conclusion, this study indicates the differences of pre-service elementary school teachers' perceptions on instructional design between face-to-face and online instruction, which implies the necessity for the development and implementation of professional development programs focusing on the perceptions on instructional design of online instruction for pre-service elementary school teachers.

In this paper, we design a covert channel based on instruction gadgets in smart sensing devices. Unlike the existing convert channels that usually utilize diverse physical characteristics or user behaviors or sensory data of smart sensing devices, we show that instruction gadgets could be exploited for covert channel establishment in smart sensing devices. In our devised covert channels, trojan smart sensing devices exchange attack packets in such a way that they encode an attack bit in attack packet to a series of addresses of instruction gadgets and decode an attack bit from a series of addresses of instruction gadgets.

This paper proposes on-chip instruction and data cache memories on RISC reduced instruction set computer) architecture which supports fast instruction fetch and data read/write, and enables RISC processor under research to obtain high performance. In the execution of HLL(high level language) programs, heavily used local scalar variables are stored in large register file, but arrays, structures, and global scalar variables are difficult for compiler to allocate registers. These problems can be solved by on-chip Instruction/Data cache. And each cycle of instruction fetch, pad delay causes the lowering of the processors's performance. Cache memories are designed in CMOS technology and SRAM(static-RAM), that saves layout area and power dissipation, is used for instruction and data storage. To speed up and support RISC processor's piplined architecture efficiently, hardwired logic technology is used overall circuits i cache blocks. The schematic capture and timing simulation of proposed cache memorises are performed on Apollo DN4000 workstation using Mentor Graphics CAD tools.

Recently, the current trend for computer based learning is moving from CAI environment to WBI environment. Most web documents for WBI learning are collected by aid of search engine. Instructors use those documents as learning materials after they evaluate availability of retrieved web documents. But, this method has the following problems. First, we search repeatedly the web documents selected by instructor. Second, there is a need for another course of instruction design in order to suggest the web documents for learner. Third, it is very difficult to analyze for relevance between the web documents and test results. In this work, we suggest WAILS(Web Agent Instruction Learning System) that retrieves web documents for WBI learning and guides learning course for learners. WAILS collects web documents for WBI learning by aid of web agent. Then, instructors can evaluate them and suggest to learners by using instruction-learning generating machine. Instructors retrieve web documents and the instruction-learning design at the same time. This can facilitate WBI learning.
