摘要
USB2.0是新一代的通用串行总线标准,其传输速度高达480Mbps,是用于高分辨率动态图像采集系统的理想接口。本文介绍了USB2.0控制器EZ-USB-FX2的性能特点,以及作者将它用于130万像素动态图像数据采集系统的开发研究工作,包括讨论系统硬件、设备固件、驱动程序及微机应用程序的实现方法。
USB2.0 is a new generation of Universal Series Bus standard, whose highest transmission rate can reach 480Mbps. This paper presents the performance and characteristics of a USB2.0 controller EZ-USB-FX2 and the author's development research by applying the controller to a motion image data acquisition system of 1.3 mega pixels/image. It also discusses the hardware, device firmware, USB driver and the host application programs of the system.
