최근, Microprocessor가 염가로 입수가능함에 따라 광범위한 분야에 걸쳐서 사용되고 있다. microprocessor를 유효하게 사용하면 컴퓨터 시스템의 설계가 용이해진다. 이 논문에서는 MMI-6701을 사용하여 NOVA의 Emulator를 설계 하였으며 연구의 성과로서는 NOVA를 Microprocessor로 대치하므로서 IC의 수가 약 3분의 1로 대치할 수 있었고, 또 Emulator의 효율화를 위하여 PROM의 Micro명령은 32bit로서 구성하여 4종류의 명령형식으로 설계 되였다. In recent years, Microprocessor have the use of extended wide fiexd because of obtainable to low price. Design of computer system be easy to do by this microprocessor apply validly. This Papers: NOVA Emulator designed by use of MMI-6701. As a result of this studies, quantity of IC changed with about a third part by NOVA exchanged with Microprocessor. Micro Instruction of PROM consist of 32bit that designed Instruction Format of four kinds.

Microarchitecture simulator is an important tool to verify and optimize the microarchitecture of a new microprocessor. Moreover. it can be use as a performance simulator to estimate the target microprocessor′s performance. And system software designers can use it as a software developing environment. This paper describes a "microarchitecture simulator for on-chip Multiprocessor microprocessor". It is a program-driven and cycle-based simulator that can execute simultaneous mutithreading benchmarks. We verified the microarchitecture of a new on-chip multiprocessor microprocessor with it and did performance simulations to estimate the performance of the on-chip multiprocessor microprocessor.

The paper introduces a switched reluctance motor drive system based on an 80C31 and an Intel 80C 196KB single-chip microprocessor control. Advance schemes are used in turn-on and turn-off angles with the power converter's main switches during traction and regenerative braking. The principles of traction speed control and braking torque control are given. The hardware and software patterns in the 80c31 and the Intel 80C196KB single-chip microprocessor control system are also presented.

Educational software tends to be monotonous without the interaction between instructors and students. An unidirectional teaching system can't overcome these barriers because the learning process is monotonous without the bidirectional communication. The advanced network system can solve these problems. In this study, a bidirectional microprocessor simulator is developed and a new teaching model is proposed using the simulator. It was named JMPS (Java Microprocessor Simulator), which is a software to teach the microprocessor principles and applications. It has two advantages. First, it can teach the principles and applications of microprocessor effectively. Second, it runs on Internet and provides easy communication between a teacher and students.

A digital controller for a discrete-data control system can take many forms. For example, they can be passive RC networks, general purpose digital computers, special purpose of mini-computer, and delay lines. With the recent advent of the microprocessor, its use as a digital controller is evident. This work discusses the hardware and software development of a microprocessor-based digital controller for a discrete-data control system. A second-order, Type 1 system is implemented on an analog computer; a Intel 80-286 microprocessor is used to implemented the controller; and, output response are obtained for step, ramp, and parabolic inputs. The results demonstrate that the microprocessor has potential as a digital controller. Finally, a brief discussion on the results indicate possible areas of improvement of the controller and future investigation.

Recently, being due to development of a small microprocessor, microprocessor have found increasing application as a digital controller in the control system. In this paper, authors analyze theoretically the continuous PID controller of a position control system with servomotor, and program the microprocessor as digital PID controller by an assembly language, and search the optimal parameters of the digital PID controller which make the smallest integral square error criterion for a performance criterion, and take experiment the indicial responses with optimal parameter. The results are following. 1) PD- behavior controller was better than P-behavior controller. 2) The smaller the smapling times of P-behavior controller and PD-behavior controller were, the better the indicial responses of the discrete system were. 3) Using a small microprocessor could replace the traditional continuous PID controller for good control.
