航天器总线管理系统的SOC设计与研究

高速、高可靠、低功耗的智能型串行系统总线是航天器进一步发展必须解决的一个关键问题。以1553B总线控制器为例,采用SOC设计方法,研究了航天器系统总线的设计和实现。首先按照1553B总线标准设计了总线管理SOC的系统结构,然后重点解决了SOC设计中的IP开发应用、可靠性设计、容错机制及低功耗实现等关键技术。采用这些SOC设计方法的1553B总线协议处理器取得了一次流片成功,为今后更高速率的航天器总线管理系统的SOC研究提供了一种思路和方法上的借鉴。

The Method and Study of SOC for Managing System of Spacecraft Bus

The intelligent serial system bus with the high speed, high reliability and low power dissipation is one of the key problems that must be solved for the further development of the spacecraft. The SOC design and implementation of the spacecraft system bus was studied, for example of the 1553B bus controller. Firstly, the architecture of the SOC used for system bus management was described according to the 1553B bus standard. Secondly, the development and application of IPs, the design of reliability, the mechanism for fault tolerance and the low power consumption in the SOC design were emphasized. The successful foundry of 1553B bus protocol processor provides a kind of referenced usage in the idea and method for the study of the managing system of the future higher speed spacecraft bus.
