摘要
新一代测控系统采用了高速串行数据传输的全数字架构,数据传输缓存性能对测控系统的功能和指标产生很大影响。针对上述问题,在介绍测控系统数据传输架构的基础上,提出了一种适用于该系统的各级数据传输缓存方法,对数据缓存机理、缓存大小及缓存读取机制进行了详细的分析和设计,并对该方法达到的效果进行了试验测试。测试结果表明,提出的方法在尽量小的缓存资源代价下,较好地实现了高速串行数据的低抖动、稳定传输,保证了测距精度及其他系统指标的性能,达到了预期的目的。
New generation measurement and control system adopts a full digital architecture of high-speed serial data transmission.Data transmission cache has a great impact on function and performance of the measurement and control system.Aiming at above problems,based on the data transmission architecture of the measurement and control system,a data transmission cache method at all levels applicable to the system is proposed.The data caching mechanism,cache size and cache read mechanism are analyzed and designed in detail.And the proposed method is tested.Test results show that the proposed method can achieve low jitter and stable transmission of high-speed serial data,ensure ranging accuracy and other system parameters,and achieve the desired goal with the minimum cost of cache resources.
