| 中文摘要: |
| 针对超声相控阵系统的高速传输需求,本文提出了一种基于FPGA的PCIe总线传输方案。实现了基于PCIe总线的相控阵数据DMA(直接存储器读写)上传、控制命令下传、发送数据缓存及驱动和上位机测试程序设计。通过实验测试了PCIe总线的DMA传输速率,可达6.5Gbit/s,并成功将该方案应用于64通道超声相控阵检测系统中,实现了超声相控阵系统的PCIe总线数据传输。 |
| 英文摘要: |
| PCIe bus solution based on Xilinx FPGA is developed for high-speed data transmission in ultrasonic phased array system. In this solution, DMA(Direct Memory Access) data up-transfer, control instruction down-transfer, data buffer, PCIe driver and test demo are designed in this paper based on PCIe bus. Test result shows that DMA data up-transfer speed can reach up to 6.5Gb/s, which satisfies the requirement of high-speed data transmission in ultrasonic phased array system. Also, this solution is successfully adopted in the 64-channel ultrasonic phased array system. |
