基于IP核的SpaceWire-PCI通信卡设计

作为一种面向航天应用的通信技术,SpaceWire具有广阔的应用前景。以IP核技术为基础,设计实现了以PCI总线为集成平台的两通道SpaceWire接口通信卡。在对板卡硬件组成进行综述的基础上,详细描述了PCI接口IP核、SpaceWire节点IP核以及驱动程序的设计方法,最后通过软件定时方法对本板卡的转换效率进行了测试。本文设计的通信卡具有尺寸小、布线简单、成本低、功耗低等特点,可以满足航天测控领域需求。

Design of spacewire-PCI correspondence card based on IP core

As a space application oriented correspondence technology,SpaceWire is now being used widely.Based on IP core technology,a correspondence card with two channels SpaceWire interface and PCI bus as an integration platform is designed.The components of hardware are introduced briefly,and the PCI bus IP core,SpaceWire node IP core and the WDM driver are discussed in detail.The conversion efficiency of this board is tested by software timing.The SpaceWire-PCI correspondence card has advantages of small dimension,low cost and low power consumption.It can meet the requirements of test and control in space fields.
