摘要
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 estab- lished in an exchange network with a heterogeneous way. Migration and reconfiguration of system functions is easily. The block da- ta 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.
