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.

This paper reports that a DDD system controlled by Stored Program Control(SPC) method was constructed and performance testresults were presented using a microprocessor instead of using conventional Wired Program Control(WPC) method. It is shown that the system was designed using a STD O/G unit which has only Point to Point(PTP) access function due to selector driving method as a O/G repeater of this system without any modification. When the system is adopted to a toll exchange system for medium and / or small city, it is expected that the system can be made with small size, high reliability and no use of conventional selector switches. It is also predicted that variation of communication route can be easily realized by simple program modification.

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.

This paper addresses the CAN based networked intelligent multi-motor control system using DSP2812 microprocessor. CAN built in DSP2812 microprocessor is used to control and monitor the multi-motor system with the inverter driving system CAN network implementation schemes and the algorithm for multi-motor control and monitoring is also developed. We configure the multi-motor control experimental system to verify the proposed algerian and the reliability of CAN networks system in the various operation of two induction motors. The experimental results show that CAN based networked intelligent multi-motor control system using DSP2812 microprocessor can carry out the real-time network based control in various speed range and the position control of induction motors.

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.
