Virtual Laboratories Of Computer Hardware Design And Research

The virtual laboratory is the resources of an important experiment teaching. There is important function for the computer haatware system virtual laboratory to reformat teaching method for computer hardware experiment course. There is the important meaning for researching the hardware virtual laboratory to promote the open type of the network experiment teaching.According to the shortage of the computer hardware system virtual laboratory and the large demand of teaching special network remote teaching, this paper brings forward the design idea and implement scheme of computer hardware system virtual laboratory. The virtual components database has been set up by abstracting mathematical modeling of electronic components in virtual experiments, according as characteristics and needs of the hardware course. Adoption the ActiveX controller technologies based COM, we design and implement the computer hardware virtual experimenting platform and provide complete virtual experiment environment. Main technologies used by are also described in the paper.The computer hardware virtual experiment system is divided into three parts: virtual components and equipments database, virtual experiment platform, virtual experiment imitate perform, and has the following native advantages: Capable of running on almost all common platforms; the virtual components database system support enlarging the new virtual components into the database; By dynamically importing, creating experiment component and facility objects; By adopting mullithread technology to implement parallel computing; Imitating run mechanism of the computer hardware system, edit and translate the assembler programs of the virtual computer; Importing the different virtual CPU chip, can imitate different type experiment on the same virtual platform; Adopting the line method to deliver the signal, can make the handling of signal approach true hardware experiments; by using double side line method in virtual experiment circuit, solve the complicated line of former electric circuit virtual laboratory. All have solved the problems of the current virtual laboratory system. At the same time, we have not only reduced the development cost but also shortened the development time. It is beneficial trial for design with implement of the computer hardware virtual laboratory.
