摘要
目前基于PCI总线的高速数据采集系统,大多采用高速A/D、CPLD或FPGA、FIFO或双端口RAM以及通用PCI接口来设计,其通用性、灵活性差,不能很好地发挥PCI总线的性能。针对这些不足,在分析了流水线技术特点的基础上,论述了采用流水线技术设计基于PCI总线高速数据采集系统的方法。按该方法设计的数据采集系统,可以达到很高的数据采集速度和数据传输速度,并具有很好的通用性和灵活性。
At present, most of the high speed data acquisition systems based on PCLD bus are designed by adopting high speed A/D converter, CPLD or FPGA, FIFO or dual ports RAM and commonly used PCI interface. Thus the generality and flexibility of the systems are not good enough and the performance of PCI bus cannot be brought into full play. Aiming at the insufficiency, and on the basis of analysis of the features of pipeline technology, the method of designing high-speed data acquisition system based on PCI bus by adopting pipeline technology is expounded. The system designed with this method offers very high speed of data acquisition and data transmlssion, better generality and flexibility.
