point在飞行试验中,1553B总线数据的实时采集对于获取鉴定测试数据具有重要的意义。1553B总线数据的实时采集过程中,按照用户预设的条件对采集到的数据进行过滤,才能得到需要的数据。然而,过滤方法得当与否直接影响采集数据的实时性。本文基于DSP和FPGA技术,设计了一种1553B总线数据过滤机制,即快速查表的方法,详细论述了此 point In flight testing, real-time acquisition of 1553B bus data is of great importance for obtaining qualification test data. 1553B bus data in real-time acquisition process, according to the user pre-set conditions for the data collected to filter, in order to get the required data. However, whether the filtering method is proper or not directly affects the real-time performance of the collected data. Based on DSP and FPGA technology, this paper designs a 1553B bus data filtering mechanism, that is, a quick look-up method, which discusses in detail
