摘要
随着1553B总线在航空航天等军事领域中的广泛应用,以及武器系统性能的提高,对1553B协议处理的智能化、处理速度、可靠性、灵活性也提出了更高的要求。以SOPC技术为支撑,对1553B协议处理器进行开发,集成PCI总线控制器核,定制高精度定时器,生成NiosⅡ系统。由NiosⅡ微处理器对系统进行控制,处理用户应用层协议,给出了问题的解决办法。通过验证可满足用户的需求,并指出进一步的研究工作。
1553B data bus is used more and more widely in aviation and spaceflight fields. But with the improvement of weapon system＇s performance, the 1553B protocol processing in bus interface must be improved in intelligence, speed, reliability, and flexibility. Basing on SOPC techniques, a method to resolve the preceding problem is designed the 1553B intelligence protocol core, PCI bus control core is integrated, high precision timer is customized, and Nios Ⅱ system is generated. The Nios Ⅱ microprocessor takes charge of controlling the system and processing user＇s application program. By verification, the method can meet user＇s needs. In the end, the next research work is presented.
