Abstract

The invention relates to an auxiliary generating method and an auxiliary generating system for an embedded device driver and belongs to the field of embedded system software design. The method comprises the following steps of: describing a device access interface, a hardware platform characteristic and a hardware device logic function by using an embedded device driver interface; saving a file in the format of XML; resolving a description file and generating an internal data structure in an internal memory; and generating a corresponding embedded device driver stub code which can be used by a developer and comprises a register access mode, a default value, a register access code and device basic performance function contents by using a pre-compiled file according to platform and system characteristics. The method and the system have the advantages of improving the development efficiency of the embedded device driver, reducing fault in a developing process, lowering developing difficulty and enhancing the portability of the embedded device driver.

Description

technical field [0001] The invention provides a method and system for auxiliary generation of an embedded device driver, in particular to a method and system for describing and assisted generation of an embedded device driver with an embedded device driver interface description language, belonging to embedded system software design field. Background technique [0002] With the development of semiconductor technology, mobile communication and mobile computing, various embedded systems have penetrated into various fields of production and life, and are gradually impacting the status of traditional PCs in many application fields. Some scholars have begun to assert that embedded system technology will become the master of the post-PC era. The importance of this field is evident. [0003] Different from the development of traditional PC, the development of embedded devices not only has its own vertical development such as performance improvement, but also its horizontal develop...
