摘要
介绍了一种新型的高速注入式图像模拟器。该模拟器以VPX总线高性能计算平台为基础,突破了VPX架构总体设计、高速串行总线传输、串/并行总线接口转换以及VPX和PCI设备兼容等关键技术,通过综合运用高速串行总线、并行总线DMA传输和乒乓控制设计技术,实现了在预定周期内大批量数据的生成和高速注入传输,为未来VPX技术在仿真领域的深入研究和应用打下了技术基础。
A new type of high speed injection image simulator is introduced. Based on high performance VPX computing platform, the key technologies such as VPX system architecture design, high-speed serial transmission, serial-parallel bus interface conversion and compatibility among VPX and PCI devices are broken through. By integrating with high speed serial bus, DMA transfers on parallel bus and ping-pong control techniques, large quantities data can be generated and transmitted at a predetermined period by the simulator. It can lay a foundation for the further research and application of VPX technology in the field of simulation.
