摘　　要：高速通信系统对通信系统的高速化与实时化要求不断提高,促使具备软硬件优势的嵌入式系统在通信领域深入发展与应用。为了满足高速通信系统的功能需求,设计了一种嵌入式高速通信系统,并构建了一种多处理器系统架构。主通信处理器选用了高性能的T2080处理器,并融合互联了多种异构网络,实现了协议与网络在不同总线间的转换与交换。系统采用MPC8548管理和维护网络交换过程,基于嵌入式Linux操作系统设计并实现了一种通信系统的高速接口。As high-speed communication systems have continuously increased requirements for high-speed and real-time communication systems,the embedded systems with software and hardware advantages have been in-depth development and application in the communication field.In order to meet the functional requirements of high-speed communication systems,an embedded system is proposed.The design of a high-speed communication system and a multi-processor system architecture have been constructed.The main communication processor selects the high-performance T2080 processor,and integrates a variety of heterogeneous networks to realize the conversion and exchange of protocols and networks between different buses.The system adopts MPC8548 to manage and maintain the network exchange process,and based on the embedded Linux operating system,a high-speed interface of the communication system is designed and implemented.
