大容量多总线的信息记录仪设计

摘要

Readers can fully understand the design method of the information recorder system based on the whole design, the design of the main board and software.According to the design idea of early computer hardware system, the information recorder mainly consists of controller, data processing unit,storage and I/O device.It is based on domestic CPU-Loongson 2F, realized 8TB data's mass storage by using SIL3124, and completed the no filtering surveillance of the data on the 1553B by using FPGA.The system has the advantages of high capacity, long time and multibus data recording, the design has been applied to a weapon system carrier successfully, and has achieved good results in practice.%可通过系统的整体设计、主电路板及软件设计全面了解信息记录仪系统的设计方法.按照早期计算机硬件系统的设计思路,信息记录仪主要由控制、数据处理、存储及输入输出四大部分构成.基于国产处理器龙芯2F,采用SIL3124存储控制芯片实现了8TB数据的大容量存储,并利用FPGA完成了1553B总线数据的无过滤监听.系统具有大容量、长时间、多总线数据记录等特点,已成功运用于某武器系统平台中,并取得了良好的效果.
