摘　　要：在对SR-IOV进行理论研究的基础上,设计实现了一种基于FPGA的虚拟化设备的数据交互模型,解决了云计算平台与虚拟设备间高速数据交互的需求。该交互模型采用多通道处理方式,减少了各虚拟设备间的影响;采用模块化设计方法,降低了设计成本与难度;同时,采用可配置的中断处理模式,对中断进行了聚集,减少了中断对CPU的压力,提升了数据交互能力。经测试验证,该交互模型能够实现数据的高速通信,同时还能平衡各虚拟设备的带宽分配。Based on the theoretical research of SR-IOV, the data interaction model of FPGA-based virtualization equipment is designed and implemented, which solves the need of high-speed data interaction of between cloud computing platform and virtual equipment. The interaction model uses multi-channel processing to reduce the impact of between virtual devices. The modular design approach reduces design cost and difficulty. At the same time, the configurable interrupt processing mode is used to aggregate the interrupts, which reduces the stress on the CPU and improves the data interaction capability. Experiments indicate that the interaction model can achieve high-speed communication of data while balancing the bandwidth allocation of each virtual device.
