Description of the principles
The innovation of the scheme is to replace the previous device driver with the characteristic value constraint. Taking the working mode of the PCI board card, the network card and the application software which are common at present as an example, the PCI equipment and the PCI driver correspond to the hardware B and the software B in the scheme, the network card equipment and the network communication application software correspond to the hardware C and the software C in the invention, and the layer driven by the previous network card is removed in the invention; the scheme creates an implementation method taking a characteristic value as a constraint condition, the characteristic value is conceptually similar to an interface communication contract, and the characteristic value can be independently made and maintained by a third-party organization. Any one C hardware can be replaced by other C hardware with the same characteristic value, and the normal operation of C software is not influenced at all. Before the former C hardware works normally, tasks such as reset, initialization, and exception handling need to be completed according to a dedicated driver control instruction. In the method proposed by the scheme, the actions are self-processed as an 'internal logic' of the C hardware, and the 'internal logic' has no relation with the A hardware, the a software, the B hardware, the B software and the C software. Another feature of the previous solution is: the data transfer between the C hardware and C software needs to be done through a driver. The implementation method provided by the scheme classifies the data communication task into hardware B and software B. Taking a USB board card, a memory card and office software as examples, the USB board card (EHCI/XHCI device) and a USB board card driver correspond to the hardware B and the software B in the present solution, and the memory card and the office software correspond to the hardware C and the software C in the present invention, and in the previous solution, a software layer such as a "Bulk-Only (BBB) program" exists between the USB board card driver and the office software, functioning as a "memory card driver", and having a software logic level similar to a "network card driver". Similarly, in the method proposed by the present solution, the software layer is removed, and the C hardware and the C software can cooperate as long as they satisfy the "eigenvalue" matching condition of the "storage constraint".
The technical effects of the invention are mainly reflected in the following aspects: the modularized connection between the hardware C and the hardware B can be realized, the logic level is simplified, the communication efficiency is improved, the associated complexity of related hardware is reduced, the appearance design of the hardware is allowed to be more freely opened, and the establishment and maintenance of a characteristic value can be independent and become the standardized constraint of the hardware C and software C.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention.
