Microprocessor is widely used in various industries. So it is very important to learn about it. But it is very difficult because students must know about both hardware and software of it. Student usually learn about it with a complete educational product in many technical high school. It make them to have no chance to mixed various electronic parts such as sensors, motors and so on. It cause them to low the creative product making ability. So we adjust new course with the arduino instead of the complete educational product to microprocessor education. It help student to high the electronic part mixing ability and the creative electronic product making ability.

본 논문은 공학계열 학생들이 어셈블리 프로그래밍을 활용하여 임베디드 시스템(ARM 프로세서)을 학습하는 교육 과정을 소개한다. 이 교육 과정은 어셈블리 프로그래밍을 통해 실제 임베디드 시스템을 실습하여 학생들이 전공 교과 과정에서 학습한 마이크로프로세서 이론을 확인하고 이해하도록 도와준다. 임베디드 시스템을 학습하기 위해 Texas Instruments 의 TM4C123GH6PGE 마이크로 컨트롤러가 탑재된 평가보드가 사용되었다. 교육 과정은 선행된 마이크로프로세서 이론 수업 진행에 맞추어 과제가 학생 개인에게 주어지며, 학생들은 결과물을 직접 시연하는 방법으로 과제를 평가 받았다. 본 논문은 이론 수업에 맞물려 진행된 과제의 일정과 과제 내용에 대해 설명한다.

PC용 마이크로프로세서는 Intel사의 아키텍처로 거의 표준화되어 있지만, 임베디드 마이크로프로세서에 눈을 돌린다면 마치 춘추전국시대의 양상을 뛰고 있다 국외에서 임베디드 마이크로프로세서로써 주목을 받는 것들 중에 하나인 Renesas Technology사(2003년, 히타치와 미쯔비시와의 합작회사)의 SuperH(SH) 계열을 소개하고자 한다. 현재 국내에서는 SuperH RISC CPU를 사용하는 교육기관. 연구소, 그리고 업체는 소수에 그치고 있지만, 한국을 제외한 국외에서는 TI사의 TMS시리즈와 같이 전력전자분야뿐만 아니라 로봇, 모바일 홈네트워크, AV기기, CIS(Car Information System) 등의 분야에도 폭 넓게 응용되고 있다. [1-4] 저자는 본 특집을 통해 SuperH시리즈에 대한 구조와 특징을 소개함으로써 국내에서도 이를 이용한 연구활동이나 제품개발에 커다란 도움이 되었으면 한다.(중략)

These days, almost all of the embedded systems have microprocessors or micro-controllers in them as their brains. So microprocessor related subjects become very important and most engineering departments have those kinds of subjects in their curriculums with practice hours. However, in most universities in Korea, the number of students in a class is more than 40 and only one teaching assistant is assigned to the class. So it is very hard job to find out an appropriate method to evaluate the students' achievements in their practice hours fairly. In this study, the author introduces some suggestions for the evaluation of the students' achievements in microprocessor practice courses. In addition to it, the author also introduces some guidelines for contents of microprocessor related subjects.

In this paper, a serial wireless LAN virtual communication module that allows microprocessors to communicate wirelessly with other peripheral devices is developed as part of a study to build an online virtual experiment system that allows them to practice virtually anytime, anywhere in microprocessor application education in electrical and electronic control engineering. The developed module is connected to the microprocessor in the virtual experiment system through serial interface. The serial data is sent to and received from peripheral devices through the wireless LAN interface of the host computer where the virtual experiment software is being performed. In order to verify the function of the developed serial wireless LAN virtual communication module, experiments were conducted in which a microprocessor in the virtual experiment system exchanged data with an Android smartphone through a wireless LAN interface of a host computer. The developed serial wireless LAN communication module is expected to enable virtual microprocessors to communicate with surrounding real devices through wireless LAN, which can be efficiently used in microprocessor application education.

Microprocessors of 8 to 16 bits have become the first step of today's computer development with excellent capability and a lot of those are still used in the educational spots. In this study, execution times of Intel series microprocessors(${\mu}ps$) available to microprocessor systems of 8 to 32 bits are obtained and compared by I/O programs. The compared result showed that execution time related to the instruction cycles of 8 bit 8051 was longer than that of 8 bit 8051 and of 16 bit 8086 by a lot of number of clocks in cases of clock frequencies at 4 MHz and at 12 MHz. In cases of really many using ${\mu}p$ clock frequencies, it showed that execution times of instructions have become faster by the order of 8085, 8086, 8051 and 80386. It can be helped to interface with ${\mu}ps$ for real time control through comparing with execution times of I/O programs by mainly many usable Intel series ${\mu}ps$ in our nation.

본 연구에서는 Atmel사의 AVR 마이크로프로세서에 적합하게 개발된 Java 바이트코드 인터프리터인 NanoVM을 자체 개발한 마이크로로봇에 이식하여 Java 언어 전용 로봇을 구현하였다. 따라서 마이크로프로세서의 구조와 회로를 모르는 학생들도 로봇을 프로그래밍하면서 Java 언어를 효율적으로 학습할 수 있다. 더욱이 최근 학생들의 프로그래밍언어 학습 능력이 떨어지면서 컴퓨터 관련학과의 프로그래밍언어 교육이 많은 어려움을 겪고 있다. 따라서 학생들의 프로그래밍언어 학습 동기를 부여하고 창의 공학적 프로그래밍언어 교육프로그램의 도입이 필요한 시점에서 본 연구에서 개발한 Java 로봇은 많은 기여를 할 것으로 기대된다.

In this study, the difference in resilience was analyzed based on the results of the microprocessor class for the group who temporarily conducted online learning due to COVID-19 and made a cross-school course. As a result of the study, the resilience value in online learning was found to be less than 150 in 12, 150 to less than 180 in 33, and 180 or more in 10. On the other hand, the resilience value in offline learning was found to be less than 150, 8 people, 150 or more, 180, 30, 180 or more, 17. Therefore, in subjects that teach hardware and software at the same time, such as a microprocessor, it is necessary to proceed with offline learning that can establish a laboratory learning environment, and when proceeding with online learning unavoidably due to COVID-19, the theory is the same as other theoretical subjects. Content should be focused on.
