But the realization of driver depends on the Driven programming model that operating system is provided, both close-coupled are together.There is not unified standard in the Driven programming model that current operation system is provided, from DLL to provide system service, all there is greatest differences to various aspects such as physical hardware modes of operation again.Therefore for same external equipment, the driver on different operating system realizes entirely different, it is impossible to multiplexing.On the other hand, distinct instruction set is used such as the x86 processor of Intel company with the Loongson processor of the Chinese Academy of Sciences between different processor.And driver is issued the most in binary form, increase income except minority and realize not providing source code, even the most same operating system also cannot straight binary multiplexing driver on different processor platform.This directly results in driver and there is serious scaling concern, depends on processor and the operating system environment of bottom, it is difficult to realize cross-platform binary system multiplexing.
Existing solution is hardware vendor or operating system developer writes special driver for different operating system environment.But it is in order at the consideration of development cost, only minority mainstream operation system platform, such as Microsoft's Window operating system, just can obtain comprehensive driver support.And these drivers underground source code, provide only the binary version of segment processor platform.For the most non-mainstream or emerging operating system, such as the operating system of domestic independent research, often can not get the support of hardware vendor, be only some the most frequently used external equipments and write driver and realize part major function.Even the driver in the such ripe operating system platform having a large number of users of Linux still suffer from supporting limited, upgrading slowly, poor reliability and the problems such as performance is the best.
Summary of the invention
It is an object of the invention to overcome the defect of prior art, mainly solve is the binary system multiplexing how realizing driver between the calculating platform that different processor and operating system are constituted, it is provided that a kind of cross-platform driver multiplex technique based on binary translation.
Owing to binary driver dependent of prior art is in floor processor and operating system, therefore to realize the difficulty that cross-platform binary system multiplexing such as is necessary for overcoming from instruction set to file format, from system service dispatch to hardware device operation to cause at the difference of aspect.
For solving the problems referred to above, the present invention provides a kind of cross-platform driver multiplex technique based on binary translation, comprising: build lightweight independent operating environment for driver in destination OS based on binary translation technology；Being respectively adopted binary translation module and realize the conversion of cross-platform instruction set, heterogeneous file form loading module realizes different file format multiplexing, provides cross platform system service with system service analog module, and common hardware control module realizes the operation of hardware device.
In the present invention, the core of multiplex technique based on binary translation is binary translation module, and this module uses binary translation technology ripe in emulator and simulator to realize the conversion of cross-platform instruction set.Binary translation technology is capable of from sourse instruction sequence to the dynamic translation of target instruction target word sequence, and on-demand can process special instruction targetedly so that the binary system across processor instruction set is multiplexing into possibility.Binary translation technology only need to disposably realize from general intermediate command set to the translation rule of new processor instruction set, has good versatility, independent of concrete hardware device and driver.For needing the driver of multiplexing, first the binary system using source instruction set is driven code operationally dynamic on-demand translation to become intermediate command set code by translation module, translates into the final binary code that can perform on new processor further according to the translation rule added.And relative to common applications, drive code itself also to have the feature that cycle of operation length, code execution flow are relatively stable and sequence interactivity is insensitive, be conducive to sharing and optimizing using binary translation technology in the impact of aspect of performance.
In the present invention, different operating system platform uses multiple different binary file format, even same operating system also supports multiple different-format.Heterogeneous file form loading module, with the binary file format under plug-in unit mode extendible support different platform, completes to be loaded into binary file from disk the work of the internal memory process space.System service analog module provides the system service consistent with driver for driver.Simulated the origin system service of lightweight by the system service on goal systems platform, and realized the redirection to service call by binary translation module so that binary system driver can complete the operation of necessity by goal systems service.The last abstract hardware operation of common hardware control module has the bottom operation of general character, separates the driver dependence for kernel environment.Make driver run and User space, common hardware control module the kernel state having acted on behalf of necessity operates, and as created the application programming interfaces on target platform, the depositor of hardware adaptor is written and read operation etc..
The invention has the beneficial effects as follows, effectively realize the cross-platform multiplexing of binary system driver, utilize the technology such as binary translation without source code with in the case of recompiling, it is achieved multiplexing existing binary system driver between different processor and different operating system.The present invention is conducive to the practical and universal of the calculating platform of various processor and operating system, especially independent research, realizes the effective support to a large amount of external equipments in the case of only needing less development cost.
