基于DSP的1553B总线接口电路设计

Circuit design of 1553B bus interface based on DSP

为提高机载火控数据采集的效率,本文以1553B数据总线协议为依据,提出一种以DSP为处理核心实现1553B数据接收的接口电路设计方法。信息交流部分由软、硬件两部分完成。其中DSP选用TI公司的TMS320C6713为处理核心,1553B协议芯片选用DDC公司生产的BU-61864,外接逻辑电路用FPGA实现。本文设计的电路所选器件应用广泛,通过机载火控数据采集实验,该设计方案合理可靠。

In order to improve the efficiency of airborne fire control data acquisition, this paper is based on 1553 B data bus protocol.And it presents an interface circuit design methods for 1553 B data receiving whose processing core is DSP.Information exchange part is completed by software and hardware.The processing core of the DSP is TMS320C6713 produced by TI Company,while 1553 B protocol chip is BU-61864 DDC produced by DDC Company.External logic circuits are realized through FPGA.These selected devices for the designed circuit are widely used. Through the airborne fire control data collection experiment,the design plan is reasonable and reliable.
