IMA系统ICP光纤通道接口板设计与实现

摘要

To improve the information interaction ability of the Integrated Core Processor(ICP)in Integrated Modular Avionics(IMA)system and achieve the goal of Fibre Channel(FC)unified avionics network,ICP's FC network interface card based on Field Programmable Gate Array(FPGA)is designed.In FPGA,it designs modules of high speed transmitting/receiving serdes and FC interface logic are designed and implemented.Meanwhile,modules including clock synchronization,power,internal memory and others are set to form a completely embedded system.ICP arithmetic element point to point connection is made to do Fast Fourier Transform(FFT)test,and to estimate the affect of shared computing resources for FC interface test slabs to ICP computing unit.Experimental results show that FC interface board transfer rate is faster,compared with the single ICP computing unit independent operation,ICP computing unit parallel operation can effectively reduce the operation time.%为提高综合模块化航电(IMA)系统中综合核心处理器的信息交互能力,实现构建航电系统光纤通道统一网络的目标,设计以现场可编程门阵列(FPGA)为核心的综合核心处理器(ICP)光纤通道网络接口板,在FPGA内部设计实现高速串行收发器和光纤通道接口逻辑,同时在FPGA外围电路上设置包括时钟、电源、存储等在内的多种配套模块,以实现一个嵌入式系统板卡.通过2台主机模拟综合核心处理器运算单元点对点连接进行并行快速傅里叶变换计算,测试光纤通道接口板对ICP运算单元间共享计算资源的作用.实验结果表明,光纤通道接口板传输速率较快,与单ICP运算单元独立运算相比,多ICP运算单元并行运算可有效减少运算时间.
