Description: This paper presents a low-power asynchronous implementation of the 80C51 microcontroller. It was realized in a 0.5 µ m CMOS process and it shows a power advantage of a factor 4 compared to a recent synchronous implementation in the same technology. The chip is fully bit compatible with the synchronous implementation, and timing compatible for external memory access. The circuit is a compiled VLSI-program, using Tangram as VLSI-programming language and the Tangram tool set to compile the design automatically to a standard-cell netlist. This design approach proves to be powerful enough to describe the microcontroller and derive an efficient implementation. Further, it offers the designer the possibility to explore various alternatives in the design space.

Description: 步进电机具有控制简便、定位准确等特点。随着科学技术的发展,在许多领域将得到广泛的应用。鉴于传统的脉冲系统移植性不好,本文提出微机控制系统代替脉冲发生器和脉冲分配器,用软件的方法产生控制脉冲,通过软件编程可以任意设定步进电机的转速、旋转角度、转动次数和控制步进电机的运行状态。以简化控制电路,降低生产成本,提高系统的运行效率和灵活性。在此基础上提出了双三拍步进电机程序控制的硬件接口电路、程序流程图和汇编程序。
-Stepper motor control is simple, accurate positioning and so on. With the development of science and technology in many fields will be a wide range of applications. In view of the traditional pulse system implanted bad, microcomputer control system proposed in this paper in lieu of pulse generator and pulse distributor, the software methods used to control pulse, through the software programming can be arbitrary set of stepping motor rotation speed, rotation angle, rotation and control the number of stepper motor operation. To simplify the control circuitry, lower production costs, improve system operating efficiency and flexibility. On this basis a two-three beat stepper motor control circuit of the hardware interface, the program flow chart and assembler.

Description: 300 km 传输线和功率补偿仿真
The circuit below represents an equivalent power system feeding a 300 km transmission line. The line is compensated by a shunt inductor at its receiving end. A circuit breaker allows energizing and de-energizing of the line. To simplify matters, only one of the three phases is represented. The parameters shown in the figure are typical of a 735 kV power system.-300 km transmission line and power compensation simulation The circuit below represents an equivalent power system feeding a 300 km transmission line.
