A system of image acquisition and transmission is developed on the basis of Cypress Coraporation's high speed USB peripheral controller CY7C68013 and OmniVision Corporation's COMS image sensor OV7620. Besides,its firmware,USB device driver and development of appli2 cation program are also introduced in detail.
This paper describes the design of portable USB mass storage devices in the embedded system based on Intel PAX255 and ARM-Linux,and analyzes in detail the framework of the Linux device driver of the USB device module in PXA255. By using the block device provided by the MTD of Linux and the protocol on USB Mass Storage Class, we achieve the USB portable storage device in this system.

This paper introduced the basic structure of virtual instrument and the basic org anization of device driver model WDM based on Windows 98/2000,and probed the basic principle and desig n method of real-izing plug and play,depending on development of WDM driver of virtual oscilloscope.
An implementation of the Graphical Kernel System ( GKS ) on IBM PC is presented in this paper. The hardware configuration, the language used to implement the system and the language binding are discribed, with emphasis on the structure of the system, the data structure , device driver, output primitive, graphical information storage, logical input device, some special auxiliary functions and some application programs developed on our GKS system,
We have successfully added the new device driver into the UNIX system V/386 3.2V binary system, during the period of designing and developing the SZII group-computer operating system. This artick mainly describes how the new device driver is added and what functions, characteristics and structure it has. In addition, some technical problems during the practice is also included.
This article is the companion piece of "the development technology of device drivers in the UNIX system V/ 386 3.2V". in this paper, how to compile, install and debug the new add on device driver is discussed.
