设计实现了一种消息重试灵活的增强型1553B总线控制器。采用不同于传统1553B总线控制器的存储器管理结构,将操作指令以OP码的形式配置在存储器的相应地址中,从而在总线控制器发生消息重试时,使重试的消息能灵活地变动,并且能重试多次。仿真结果表明,该增强型总线控制器使得消息重试更加灵活,有效地提高了消息重试的成功率和数据传输的可靠性。该总线控制器已应用于1553B协议芯片,并经流片验证。 Design and implementation of a message retry flexible enhanced 1553B bus controller. Different from the traditional 1553B bus controller memory management structure, the operating instructions in the form of OP code configured in the memory address, so that the bus controller retry of the message, the retry of the message can be flexibly changed, And can try again many times. Simulation results show that the enhanced bus controller makes the message retry more flexible and effectively improves the success rate of message retry and data transmission reliability. The bus controller has been applied to 1553B protocol chip, and verified by the chip.
