Implementation method used for embedded system software development tool

The invention discloses an implementation method used for an embedded system software development tool. The implementation method comprises the following steps of: a1, connecting a multi-platform compilation tool chain with a development tool, so that compiler parameters of different operating system platforms and different central processing units serve as the inlet of a corresponding tool chain in the multi-platform compilation tool chain; a2, establishing an independent development environment which is provided with compiler parameters corresponding to a target operating system and a target central processing unit and a unified catalogue structure and comprises a file required by the project engineering for the project engineering to be developed through the development tool; and a3, selecting a corresponding tool chain in the multi-platform compilation tool chain for compiling so as to generate a target file in the process of compiling the project engineering according to the compiler parameters in the development environment. The implementation method has the beneficial effects that a complex and customized multi-module development mode is realized, and cross-platform development compilation of different operating systems and processors can be realized, so that the development efficiency is improved, and the error rate is reduced.
