摘　　要：在高速阵列信号处理系统中,数据采集端与信号处理主机之间的数据通信量非常的大,为了保证系统性能,对数据传输卡提出了更高要求,传统基于PCI总线的数据传输卡已经不能满足系统需要,作为PCI总线的升级版——PCI-X总线,不光提高了总线时钟频率,还拥有更为合理的传输时序与中断响应机制,是新一代阵列信号处理系统的理想总线。本文介绍了基于PCI-X总线的数据传输卡的设计与实现,并对基于IPCore的PCI-X总线接口实现进行了详细分析,从仿真与实际使用效果验证了基于PCI-X总线的数据传输卡达到了设计性能。In high speed array signal processing system, enormous amount of data needs to be communicated between data collector and the host. To ensure the communication performance, higher requirements for data transmission card are demanded. Conventional PCI bus data transmission board can no longer satisfy the system requirement. As the upgrade product of PCI bus, PCI-X bus has the higher bus clock frequency and also has better transmission time sequence and interruption response mechanism. We introduce the design and implement of PCI-X bus data transmission board,and analyze the PCI-X bus interface implementation based on IP Core in detail. The simulating and experiment result show that the PCI-X bus data transmission board satisfies the design performance demand.
