摘要
针对目前自动测试系统中要求测试信号传输距离远、传输速度快、传输信号种类多、系统工作环境恶劣等问题,设计并实现了基于PXI总线的多路高速数据传输卡。采用FPGA实现了自主化的UART和PXI接口模块,与专用接口芯片相比,具有传输速度快、灵活高效的特点,增强了系统的集成度、稳定性和可靠性。
A multi- channel high- speed data transmitter based on PXI bus is designed to meet the requirements of long- distance and high- speed transmission. The UART module and the PXI module are both self- designed and accomplished with FPGA. The bus modules and users＇ modules are combined closely to promote the integration, stability and reliability of the whole system.
