| 摘 要： | 基于PCI总线的高速数据采集设备驱动开发，其核心问题是驱动程序必须要有快速的实时响应能力和灵活的数据接收结构。分析了限制驱动程序高速数据传输的瓶颈，提出了分片、分帧的数据传输结构，给出了基于该结构的设备驱动设计思路。数据传输速率可达85MBps，与计算机的配置无关。

| Abstract: | The device driver must have quick response and flexible data structure for the device driver development of high speed data capture based on PCI bus. A multi-slot and multi-frame data structure was presented in this paper after the bottleneck of high speed data capture was analyzed, and a guideline to the design of the device driver was also presented. The data capture speed can be 85MB per second and it is independent of the computers' configuration. |

| Keywords: | PCI bus high speed data capture device driver data tranform structure |
