基于PCI总线的高速数据采集接口的设计与实现

Design and Implementation of a High-speed Data Collection Interface Based PCI Bus

PCI总线接口控制器的设计是基于PCI总线的应用设计的关键所在。本文在介绍PCI9054接口控制器的基础上,给出了一种通用的高速数据采集接口的设计,并提出了一种新的包括PCI9054单周期读、写和DMA读操作的VHDL状态机设计。经测试证明,该接口的数据采集速率能稳定的达到200Mbit/s。

The PCI bus interface controller design is its key techniques to application based PCI bus. This paper introduces the PCI9054 interface controller and presents the design of universal high-speed data collection interface.A novel VHDL state machine design including single-clock reading and writing and DMA reading of PCI9054 was proposed.h has been verified that data collection speed was 200Mbit/s steadily.
