Method and device for sharing experimental equipment by computer hardware courses

Abstract

The invention belongs to the field of computer experimental apparatus and provides a method and a device for sharing experimental equipment by computer hardware courses. The method comprises the following steps of: connecting a universal FPGA (Field Programmable Gate Array) development board with a computer by virtue of USB (Universal Serial Bus); installing experiment software with a custom function in the computer; designing an interface circuit in the FPGA and connecting the interface circuit with a student experiment module by virtue of a universal internal port; and designing a control circuit in the FPGA, and controlling data communication between the experiment software and the student experiment module. The method and the device meet the requirements of a digital logic circuit, a computer composition principle, a system structure, an interface technology and experiments of hardware, such as an embedded system, for the experimental equipment, and can be used for making full use of the experiment environment and improving the resource utilization rate, facilitating the upgrade and function expansion of an experimental system, alleviating the load that students need learning multiple experiment platforms, and meanwhile providing a more visual experimental process and result for a user; and the device can be used and operated by the students and teachers conveniently.

Description

technical field [0001] The invention relates to a method and device for sharing experimental equipment in computer hardware courses, belonging to the field of computer experimental instruments. Background technique [0002] The importance of practical teaching of computer and related professional hardware courses in colleges and universities is self-evident, but for a long time, the experimental platforms of each course are relatively independent. Such as TEC series experiment box for computer composition principle, TPC series experiment box for microcomputer principle and interface, TPE and TDS series experiment box for digital logic circuit, TEB series experiment box for single-chip microcomputer and embedded system, etc. These box-type experimental platforms generally have the following problems. First, the cost of the experimental platform is high. Its control circuit is composed of a single-chip microcomputer and related logic. The design is fixed and the control is com...

Problems solved by technology

The general-purpose FPGA development board method solves the problems existing in the independent experiment box, reduces the cost, improves the utilization rate of experimental resources, and reduces the burden on students who need to learn multiple experimental platforms, but there are still some problems, such as verifying the experimental results, need to Lead the internal logic to the external pins of the chip. At this time, the number of inputs and outputs of the experimenter is limited by the pins of the FPGA, which limits the flexibility and design scale of the experimenter's design. Another example is the lack of general experiment software. As a result, the experimental phenomenon is not intuitive and the experimental debugging is inconvenient. After the students design is completed, in addition to checking the correctness of the experimental design through simulation, they can only verify and judge the design by inputting information through the development board switch and displaying the results through the indicator light. correctness
