| Abstract: | In order to resolve the problem of the hardware environment differences in building embedded system developing platform,this paper proposed the design solution and its realization method of a high portability Hardware Abstraction Layer(HAL) and then give the specification of its realization.HAL gives underlying layer's encapsulates specification and offers operating interface to upper layers' software design.HAL's introduce shields the differences of underlying hardware,improves embedded system developing platform's openness and also shortens the development period of the embedded products effectively. |

| Keywords: | embedded system developing platform HAL portability HW/SW co-design |
