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。
In order to improve the information exchange capability of the integrated core processor in the integrated modular avionics (IMA) system and achieve the goal of building a unified network for the fiber channel of avionics systems, a comprehensive core processor based on a field programmable gate array (FPGA) (ICP) Fiber Channel network interface board designed to implement high-speed serial transceivers and Fiber Channel interface logic within the FPGA while providing a variety of complementary modules including clock, power supply, memory, etc. on the peripheral circuits of the FPGA to achieve a Embedded system board. Through two host simulation integrated core processor computing unit point-to-point connection parallel FFT calculation to test Fiber Channel Interface Board ICP computing unit shared computing resources role. Experimental results show that the transmission rate of Fiber Channel interface board is fast, and the operation of multiple ICP units can reduce the computing time effectively compared with single ICP unit.
