A microcomputer laboratory for juniors majoring in computer science was developed. It enables them to observe fundamental behavior of a computer by directly giving instructions to the CPU using a programmable diode array. The laboratory also includes experiments to synthesize a small microcomputer, with which advanced subjects such as interrupt processing and queue data structure usage are studied. As an application, a primitive interrupt‐driven graphics editor has been designed and implemented. Various circuit components were mounted on three panels, which facilitate for the students to construct required circuits. A personal computer has been used for software development. 相似文献

MV10 is an MCU which consists of PWM,ADC,CAN and some other function blocks.It is designed for car body's control.Advanced peripheral bus (APB) is a low speed AMBA bus connecting low-power peripherals.This paper presents an implementation of APB interface for MV10 MCU.After that,MV10 can be integrated into any AMBA system on chips (SoCs) easily.We have built a multi-core system with ABMA to verify this design.In this system ARM9 is a main processor mounted on AHB and MV10 acts as a low-power and low-speed slaver on APB.Before building this system,some operations are encapsulated into a task with dedicated ID.MV10 works as a co-processor with ARM by acquiring task ID from ARM.The result of simulation indicates that MCU can work well as expected.Based on our design,MV10 can be mounted on any AMBA system from now on. 相似文献

相对于目前在规定道路下进行一定条件限制的等速油耗试验,采用底盘测功机进行汽车燃油经济性试验更科学。由于采用计算机模拟道路、气候、风速、湿度等客观试验条件,确保试验的过程更接近真实车辆使用情况,获得的油耗也更接近实际。对底盘测功机台架试验中模拟各种实际行车路况和环境的计算机系统进行开发,并进行车辆在底盘测功机上的燃油经济性试验,利用计算机系统模拟一般道路状况下车辆的等速行驶,并对油耗进行统计。试验结果表明,这种方法具有很强的可操作性,可作为一般企业或检测机构进行油耗试验的首选方法。 相似文献

This paper describes a microcomputer interfacing course for computer science students. Students build simple logic circuits to interface a microcomputer with real‐world devices, such as stepper motor and digital displays, and program the computer to monitor and control these devices. Programs are written in Pascal and assembly language. The emphasis is placed on applications rather than on theory. This course is especially designed for computer science students who are proficient in software programming but have little or no experience in electronics. The experiments described here have been developed on the Apple ft microcomputer, but they can be easily adapted to other microcomputers. 相似文献

随着我国推进生态环境保护工作的全面开展,在污染防治、落实环保措施等方面取得了积极进展和成效。与此同时,在高等教育领域,高校对实验室安全与环保工作也越来越重视,尤其是实验室废液管理方面,表现出精细化的管理模式和专业化的处置方式。然而,虽然实验室废液管理取得了一定成效,但仍存在分类不合理、标识不规范、监管不到位等问题。通过设计实验室废液信息管理系统,能够规范废液管理,辅助处置过程,提高处置效率。同时,借助系统可以优化废液信息的统计分析,实现废液信息的动态监管,保证数据的有效性和可追溯性,为后续制定和完善分类标准,加强废液管理提供有效支撑。 相似文献

双被告制度创设伊始是"解决行政复议现实问题的中药"，实际却"制约行政复议改革"，如此反差值得深思。2020年《中华人民共和国行政复议法（修订）（征求意见稿）》对程序标的和复议决定效力的改变否定了双被告制度，应值此契机进行制度检视。为纠正维持率过高，基于"复议决定可诉"和"一体化理论"构建，双被告制度具有强烈问题导向性，存有降低维持率有限、实践中附带影响大、理论内在冲突等弊病。应取消双被告制度并围绕行政复议新时代功能定位就复议队伍和监督体系进行重构，助力行政复议法治愿景实现。 相似文献

This paper starts from the assumption that learning is promoted through confronting students with the inconsistencies entailed by their own beliefs. The issue is explored in the domain of electricity in the context of simple DC circuits. Previous work is used as the basis for the construction of a programme of work that is undertaken by a group of students. This programme entailed the development of a computer-based modelling environment called ELAB. The underlying design principle is that students should be able to model electrical circuits at a level which permits them to express some of their explicit (possibly mistaken) beliefs about relevant concepts. Other, implicit, beliefs should also be detectable through use of the system. The results derived from observation suggest that computer-based modelling facilities can provide advantages over approaches exploiting other media. In particular, such systems can be used to promote the kinds of intellectual conflict that are believed to be beneficial. 相似文献
