Abstract

The invention discloses an experimental device for the computer hardware series course. The device comprises a downloading circuit, an experimental core module, an expansion module, a memory and a communication interface circuit, wherein the downloading circuit is used for downloading the hardware codes and experimental test programs for the experiment; the experimental core module and the expansion module are used for configuring logic functions according to the hardware codes to execute the experimental test programs; the memory is connected with the experimental core module through a data bus, an address bus and a read / write control line and used for storing the experimental test programs, the hardware codes and data; the communication interface circuit is used for communicating with the outside; the experimental core module is an FPGA (field programmable gate array); and the expansion module is a CPLD (complex programmable logic device). The experimental device disclosed by the invention can be flexibly configured according to the content of experiment, thus the content of experiment is rich that the component experiment as well as the systemic experiment about the computer hardware series composition can be realized.

Description

technical field [0001] The invention relates to the field of electronic computers, in particular, to an experimental device used for computer hardware series courses. Background technique [0002] At present, the domestic computer hardware series course experiments mainly use separate devices for experiments. Most of the components such as calculators use off-the-shelf functional chips, resulting in a relatively fixed structure of the model machine used in the computer hardware series of experiments, thus affecting the flexibility, systematicness and openness of the experiments. The use of off-the-shelf functional chips makes it impossible to adjust the experimental content, resulting in experiments that are mainly verification-based experiments, and it is difficult to carry out more flexible design experiments; the use of fixed-structure experimental devices makes most of the experiments that can be carried out are verification-based experiments. Component experiments that...

Most of the components such as arithmetic units use off-the-shelf functional chips, resulting in the relatively fixed structure of the model machines used in the experiments of the computer hardware series courses, thus affecting the flexibility, system and openness of the experiments

The use of off-the-shelf functional chips makes it impossible to adjust the experimental content, resulting in experiments that are mainly verification experiments, making it difficult to conduct more flexible design experiments; the use of fixed-structure experimental devices results in most of the experiments that can be carried out based on verification The component experiment mainly lacks the system experiment content that can reflect the overall composition of the computer; at the same time, the experiment is too dependent on the inherent chip, and it is difficult to conduct open design experiments, so that the experimental content cannot be closer to the teaching content
