Existing solution has following several, but all has open defect.First kind is to realize above-mentioned application again by special developer on autonomous platform.Obviously this method is all unrealistic on resource and cost.Second kind is to rely on the community that increases income to provide the compatibility with source code to realize, recompilates on target platform then and generates binary executable.At first, therefore can't guarantee the support that application program obtains continuing because the community that increases income can't provide effective maintenance for compatible program.Difference between secondly compatible realization and original program also can cause the decline of user experience.The last compatible potential problems such as security, stability and program feature of realizing also existing.Last a kind of binary translation technology that is to use is translated into the target platform binary program with the binary program on the source platform, then operation.This method has the versatility advantage, and can loyal reaction original program function.The binary translation instrument that with QUME is representative is supported on a plurality of platforms.The major defect of this method is that existing binary translation instrument can not support to exist mutual isomery program, promptly the binary program on the heterogeneous platform needs and local program carries out alternately, such as calling background data base or operate that the local hardware driving prints etc.
Summary of the invention
The problem that the present invention mainly solves is how to realize striding the binary translation instrument to carry out inside and outside program interaction, thereby improves the cross-platform versatility of isomery program.
Carry out because existing binary translation instrument has only been considered the translation of heterogeneous platform program in design, therefore in the process of implementation, every by this routine call to any code all can carry out binary translation.The outside local program also can't directly be called the heterogeneous platform program simultaneously, because be that variation has all taken place for function entrance or parameter transmission.
For addressing the above problem, the technical solution adopted in the present invention is: based on existing binary translation instrument, module when expansion translation is wherein resolved and moved promptly increases mutual expansion module of isomery and mutual jump list, and overall architecture as shown in Figure 3.
The isomery program interaction method based on binary translation that the present invention proposes utilizes cross-platform executive routine to carry out mutual between the heterogeneous platform program with the binary translation instrument that relies on exactly.
Among the present invention, the described exchange method that carries out between the heterogeneous platform program is: utilize cross platform program all to be subjected to the characteristics that the binary translation instrument is controlled fully in translation and execution, realize calling mutually of local code and cross-platform code.
Isomery program interaction method based on binary translation of the present invention, wherein, extended dynamic binary translation instrument is for the translation of function call, intercepts and captures all cross platform programs to the calling of external program, and the process of proxy call.
Isomery program interaction method based on binary translation of the present invention wherein, for the binary translation instrument provides packing support to the cross platform program function interface, realizes the local compatibility of calling with the cross platform program external interface.
Isomery program interaction method based on binary translation of the present invention comprises on the specific implementation: the inner isomery program of outside local routine call and two aspects of inner isomery routine call outside local program.
The inner isomery program of outside local routine call: for this kind interactive mode, the calling interface that inner isomery program often needs to expose agreement by system service initiates to call for other programs.The mode of creating interface depends on the system of operation, such as linux system many with file as calling interface, the Windows system is then in the majority as interface with registry entry.Therefore need expand the binary translation instrument, intercept and capture the interface creation operation of isomery program.The interface operation that this is manipulated under the home environment is simulated then.And need all local interfaces of monitoring, and the isomery routine interface is handled function calls when receiving to be converted into when local program calls by the isomery program creation.Call related parameter and need carry out suitable conversion, position, size and sequential scheduling agreement such as storage all may there are differences under different platform.
Inner isomery routine call outside local program:, at first need the interface specification of unified External Program Interface under isomerous environment for this kind interactive mode.When the isomery program is loaded,, note all outside call instructions of isomery program by expansion for the binary translation instrument.And the destination address and the outside local interface of these call instructions is mapped one by one.Monitor the execution of these call instructions then when operation, interactive module is according to the corresponding relation calling external program when call instruction is triggered.Call the processing of parameters needed transmission need carry out calling inner isomery program as the said external local program equally the time, unique difference is that the mode of handling needs to reverse.
The invention has the beneficial effects as follows, effectively realized the mutual of the inside and outside program of binary translation instrument, make and to call mutually and to cooperate between cross-platform isomery program, thereby the cross-platform scale-of-two that improves the isomery program is multiplexing.The present invention helps non-mainstream platform, especially is the system of core with the independent research processor, realizes the quick support to existing binary program.And can effectively reduce march toward practicability and obtain popularizing required cost of development input of these platforms.
