The Research Of Baseband Data Switch System Based On RapidIO

The fast development of embedded processing technology is posed a serious challenge to high-performance embedded system high-speed interconnection.In order to cope with such challenges and meet the needs of embedded system development,the industry's leading semiconductor and system manufacturers work together to set up a high-speed Internet Protocol-RapidIO.This protocol can support arbitrary topology and point-to-point operation,provide effective congestion control,high transmission efficiency and reliabilityBecause of the fully consideration of RapidIO interconnect technology in respect of routing,switch,and ease of use,it will be gained far-ranging applications in the field of embedded system,wireless base station of 3G/B3G and high-performance digital signal process system.The application of serial RapidIO in next-generation wireless base station is in-depth researched in this thesis.Firstly,the RapidIO key technologies and the tendency of wireless base station development are discussed.Secondly,according to the application of RapidIO in the field of wireless communications,a design idea used serial RapidIO interconnect architecture in next-generation wireless base station is put forward.Thirdly,the feasibility and technical advantages of this design is certificated on the existing structure of base station.From the theoretical analysis and experimental results obtained,compared with other interconnection architecture,RapidIO has a significant advantage in terms of functionality,performance and cost. To the embedded systems especially the wireless base stations,Serial RapidIO interconnect technology is the best one.
