Abstract: Combining with the features of the embedded operating system design and aiming at 486 target board, the independence between the software and the hardware is accomplished by its BSP during the transplanting of VxWorks OS. This paper describes the conception and the start-up flow of the BSP, and introduces its design process. Combining with the practical project, the implement of VxWorks grounded on 486 and the method of how to add applications are given..
