【摘要】 无线通信中基带处理器与系统控制器接口是UT斯达康公司无线通信软件研究中心设计的user equipment模拟器中的数据传送通道的一部分。这个接口是个通用的电路，它能够应用于那些需要DSP的link port端口的所有领域。 本文在综合考虑接口电路在系统中的作用，以及对接口的性能、时序、速度、占用内存等要求条件下，从结构、算法、资源条件等方面综合考虑对接口进行设计。一方面，接口电路设计的重点在于对天线数据的整理排队，采用了双端口RAM配合计数器实现数据的排队，另一方面，接口电路设计的重点是数据的传输，这部分主要完成和DSP的linkport的接口，使数据高速传给DSP处理器，进行后续处理。 这个项目按照自上而下的设计流程，从系统划分、编写代码、RTL仿真、综合、布局布线，到FPGA实现。在设计的不同阶段使用了不同的EDA工具，包括Modelsim、Synplify、Quartus等等。 笔者在整个设计过程中，研究了接口电路的设计技术，提出了无线通信中基带处理器与系统控制器的接口模型；设计了数据排队与数据接口，在数据排队模块提出了横向输入、纵向输出的算法。更多还原

【Abstract】 The baseband processor and system controller interface in wireless communication, which is UTStarcom, the center of researching wireless communication software a part of data transmission passway of simulator of user equipment . The interface pieces of in common use circuit, it can apply in all field of port, which need link port of DSP.This text consider the role of interface circuit in system synthetically , and consider the constraints of time sequence, speed, take memory etc.to design to the interface synthetically. On one hand, the focal point that the interface circuit is designed lies in lining up the arrangement of the aerial data, have adopted one pair of ports RAM to cooperate with the counter and realize the lining up of the data , On the other hand, interface focal point that circuit design transmission of data, part this finish mainly and interface of linkport of DSP, make data transmisst to DSP processor at a high speed , go on follow-up punish.The project was designed according to the procedure from top to bottom, including dividing module , writing codes , RTL emulation , synthesizes from system , placement and routing , get to FPGA and realize. Use different EDA tools , including Modelsim , Synplify , Quartus ,etc. at different stages of what has been designed.I have studied the designing technique of the interface circuit in the course of designing entirely, have put forward the interface model with the processor and system controller of the base in wireless communication; Design data line up with data interface, line up module propose horizontal input, vertical algorithm that output in data.更多还原
