Design And Implementation Of The Virtual Lab System For The Principle Of Computer Organization

As a new lab-teaching mode of virtual-lab, which supplied a gap to traditional lab equipments, also it's a new develop direction to lab-teaching. The Principle of Computer Organization is an important, professional foundation courses for computer science. For such courses, which needs strength practice, experimental phase is a pivotal steps for study courses well. Combined with the Principle of Computer Organization lab-courses of this paper, relevant modeling of virtual-lab system and method of simulation will be researched, consequently raised a virtual lab system for the Principle of Computer Organization (VLPC for short) issue, which include design of idea and realization scheme, ultimately realized a basal virtual lab system. This system is a parts of sciences technology department of Hebei Province project"network virtual lab for principle of computer organization system".Virtual lab system for the Principle of Computer Organization use C# language establishes an analog lab-surroundings on .NET workplace. Make use of virtual-components (or circuit expression) represent actual components, allows students using virtual-components to establish logistic circuit, design ALU or controller or other function parts, etc, and finally buildup CPU. In process of virtual logistic circuit emulation, students could dynamic seen float instruction or data and each virtual-components word status. By this way it is greatly enhance students abilities about handmade or solve actual matters, and put forward a whole new lab-teaching mode for students.This paper and virtual lab system for the Principle of Computer Organization accomplished independently by professor geng's guidance, as follows its main work: 1. Raised design purpose and blue print of virtual lab system for the Principle of Computer Organization. Analyze holistic frame of this system, and each module basic function will be confirmed. 2. Combined with practical instance, researching methods of modeling, defining abstract model of virtual-components, encapsulating this former based on .NET groupware technology, finally received favorable independency, patulous and repetitive-used of virtual-components. 3. This paper researched method of simulation to model of discrete-event, which used to virtual logic lab system, set immovable-delay model to virtual-components of an apparatus, and put forward a new way of event-synchronous to which kind of virtual logic components'simulation have immovable-delay. In search of Chinese technological magazine library and doctoral or excellent master's paper library, unseen correlative reports about this paper's ways and means. 4. As an APP example, use this system to establish 8-bit CPU mainframe model, and design repertoire of this model use Micro-program control's technology, also use input assembler accomplish relevant simulation.Flexible modeling, easy to realization, have highly efficiency of executive of this system, and could widely used in teaching of undergraduate or technological courses,as a supplement of hardware lab-device. This simulation system design of idea is also good use for reference to other similar systems.
