Embodiment Construction

[0018] As shown in FIG. 1 , the computer device 20 is connected to the hardware device 10 , and the information interaction system 300 communicates with the hardware device 10 based on the computer device 20 . Wherein, the hardware device 10 may be a printer, a camera, an optical drive test device, and other various test devices connected to the computer device 20 , and the computer device 20 is a common computer.

[0019] The computer device 20 includes: a global descriptor table (GDT, Global Descriptor Table) 400 , a section object (Section Object) 500 and a privileged instruction module 600 .

[0020] The global descriptor table 400 is used to store descriptors, and each application program has a corresponding descriptor stored in the global descriptor table 400 . The content of the descriptor includes the access rights of the corresponding application.

[0021] The section object 500 is a tool for reading and writing the global descriptor table 400 , but the section objec...

Abstract

An information interactive system comprises gate structuring module for utilizing node object to structure a call-gate in global description symbol table and application program module for using said call-gate to call on privilege command of central processor in privilege command module in order to obtain right for carrying out communication with hardware unit.

Description

【Technical field】 [0001] The present invention relates to an information interaction system and method, in particular to an information interaction system and method based on communication between a computer device and hardware equipment. 【Background technique】 [0002] Computers have been widely used in production and life, and there are more and more hardware devices connected to computers. The device drivers of different hardware devices or hardware devices produced by different manufacturers are also different, so when installing new hardware devices to There are many troubles when you are on the computer. For example, when installing a new hardware device on the computer, the new hardware device cannot be used because the driver disk cannot be found, or the driver file location cannot be found, or the user does not know what the driver is. . [0003] A device driver is a program code that enables the computer to communicate with various hardware devices. The operating...
