摘要
根据1553B数据总线协议及其接口技术要求,设计了一种基于PCI局部总线的1553B总线接口卡。系统使用PLX公司的PCI9052和DDC公司的1553B协议芯片BU-61580,通过FPGA芯片EP1C12B进行PCI协议和1553B协议的转换,使用DSP控制器TMS320F2812作为下位机的主控单元,并编制了接口卡驱动程序,实现了1553B总线和PCI总线的转换。
A 1553B bus interface card based on PCI local bus was designed according to the data bus protocol of 1553B and its requirements of interface technology.A PCI9052 chip made by PLX Company and a BU-61580 chip from DDC Company are adopt in this system.Both of the protocols of PCI and 1553B are transformed by a FPGA chip EP1C12B.A DSP controller TMS320F2812 is used as the main control unit of lower computers.The driver of interface card was compiled.The transformation of 1553B bus and PCI bus was realized.
