The design plan is proposed on the basis of analyzing the principle of hardware structure of RTR in CDMA2000 BTS system.According to the function that polo shirts needs to achieve, BSP is divided into several modules. The implementation of each module is discussed in detail. In this dissertation, a hierarchical design method of communication chi flat iron port between CPU and chi hair straighteners is specially proposed. The interface is simplified into physical layer, link layer and application layer to reduce the complexity of the realization. Meanwhile, the reliability and scalability of the interface between Lacoste Polo Shirts and DSP is also guaranteed. Therefore, the information exchange between cheap ralph lauren polo shirts and DSP becomes better.The realization of VxWorks BSP is based on C language and a small amount of assembly language. Some of these modules codes have a certain of reusability and can be transplanted to other hardware platform. Finally, this dissertation tests some main modules of BSP and verifies its reliability.
