The Study And Implementation Of Embedded Linux Device Driver Based On PCI Local Bus

With the rapid development of the computer and embedded technologies, more and more electronic devices are controlled by microprocessors. Nowadays most of the CPUs and peripheral equipments offer PCI bus interface, because PCI bus has become an extensive and universal bus standard in the computer system.Linux is popularly applied because of its speciality of free and open codes. The application based on Linux kernel in the Embedded Operating System is imperative for low cost. And the DVB-IP Project which belongs to the National"863"High Tech. Plan uses the very PCI Bus based on Linux,so it's very important, practical and portable to apply and develop the Linux Device Driver.This thesis has firstly studied the Features, Transfer Control Mechanism and Configuration Technology of the PCI Local Bus, also studied the PCI Interface of DM642, the characteristics of Linux OS and Linux Device Driver, has expatiated the hardware development of DVB-IP Gateway, deeply analysed the key technologies of developing...
