Description
Technical field
The invention belongs to embedded computer technology field, more particularly to a kind of structure side of plug in software module
Method and device.
Background technology
Because there is larger difference in various Embedded Application targets so that embedded hardware and operating system also each not phase
Together, even if the application program of exploitation said function, it is also desirable to for being programmed on specific embedded platform；User is caused to exist
Require a great deal of time in the exploitation of application software and energy, and the application software for developing can't be transplanted to which
His Embedded Hardware Platform；Therefore, the code of embedded application software does not possess reusability, and this is that embedded development faces
Maximum bottleneck.
Embedded system is primarily present following some problem at present：
1. the maximum feature of embedded system is exactly otherness, is applied to the embedded product and equipment of different occasions, nothing
By being from form or functionally, to be all very different.
2., in the development process of routine, user arranges needs and proceeds by Software for Design and written in code, from actual feelings
From the point of view of condition, due to the changes in demand that vary and may occur at any time of demand, personal code work there is no reusability, this
If just meaning demand occurs certain change, whole code all can may be write again, and this not only delays opening for user
The progress of sending out, and the robustness and reliability of code are have impact on, it is that the functional realiey of user equipment brings huge risk.
3. the exploitation of built-in system software is closely related with the device driver of bottom.User will realize setting hardware
Standby operation just must be completed by device driver, be all directly to carry out device drives by user program in conventional exploitation
Program is called, and this mode requires that the developer of application program needs the driving journey of the hardware design to bottom and the equipment
Sequence has enough understandings；In addition, when the access of device driver is carried out, the software interface that driver is provided is not general
Property, user is very inconvenient in application call.
4. device driver can be defined as a good inside programming interface, and the work of complete concealing device is thin
Section, the operation of user be by one group it is standardized call performing, these are called to be mapped to and are acted on by device driver
In the peculiar operation of equipment of actual hardware.This is one and seems perfect invoked procedure, but actually due to the thousand of hardware device
Differ from ten thousand other and distinct program person programmings to be accustomed to, for same equipment, the driver that different programmers writes out can
Can different style, there is provided operate interface may be not quite similar.This does not obviously have versatility for user operation, when with
When the application program that family is write needs call driver function, user must also consider to use which function performance, pass
Which parameter is passed, the detailed problems such as return value whether are needed, it is clear that the development rate and versatility of software code is have impact on.
