针对航电系统中多芯片间互连通信速率低下的问题,在对RapidIO 互连技术研究的基础上,提出了一种块数据传输方案。以软件异构的方式在交换网络中建立多个实时通信链路,易于系统功能的迁移和重构,采用块数据通信机制实现数据的发送与接收,传输速率相比传统消息机制通信方式有了很大的提升。设计具有很强的通用性和可移植性。

In view of the problem of low efficiency between the chips in the avionics, a block data transmission scheme based on the research of the RapidIO interconnection technology is proposed in this paper. Multiple real-time communication links are established in an exchange network with a heterogeneous way. Migration and reconfiguration of system functions is easily. The block data communication mechanism is used to transmit and receive data, and the communication rate is greatly improved compared with the traditional message mechanism. The design has a strong versatility and portability.
