Wireless Communication Hits The Research With The Processor And System Controller Interface Technology Of The Baseband

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.
