Abstract

The invention provides a method for compatible operation of PCI (peripheral component interconnection) hardware applications. The method includes: when PCI hardware is operated by at least two applications, starting a service program, applying the service program to obtain a data structural list of the PCI hardware, and releasing the data structural list to all applications operating the PCI hardware to enable the applications to operate the target PCI hardware according to target PCI hardware information in the data structural list. Using the method and the device for compatible operation of PCI hardware applications solves the problem of abnormality when the PCI hardware is simultaneously operated by multiple applications, and enables the applications to operate compatibly.

Description

technical field [0001] The invention belongs to the field of hardware control, in particular to a method and device for compatible operation of PCI hardware application programs. Background technique [0002] PCI (Peripheral Component Interconnection, peripheral component expansion interface) hardware applications must be based on the underlying PCI hardware driver. At the operating system level, all hardware resources will be used as a handle (Handle, essentially a specific integer number) Recognized and used, due to the particularity of the PCI device hardware, when a process occupies the handle of this device, other processes will generate errors in the operation of this device (including scanning, opening, etc.), this is the PCI hardware driver The process exclusivity of the program. [0003] In actual engineering practice, it is often necessary to use multiple application programs with different application purposes to operate different PCI devices at the same time or ...
