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。
With the wide application of the 1553B bus in military fields such as aerospace and the improvement of the performance of the weapon system, the 1553B protocol has also been put forth higher requirements in terms of intelligence, processing speed, reliability and flexibility. With SOPC technology as the support, the development of 1553B protocol processor, integrated PCI bus controller core, custom high-precision timer, generating Nios Ⅱ system. By Nios Ⅱ microprocessor system control, user application layer protocol, gives the solution to the problem. Validated to meet the needs of users, and pointed out further research work.
