Research And Development On Device Drivers Of Embedded Digital Video Record Sysytem

This thesis designs and complete the device drivers of the digital video record system, based the research on the kernel and device drivers of linux.First , this thesis do some research on the device driver of the embedded linux, include the framework of linux kernel, mechanisms of linux kernel and the knowledge of linux device driver associated and linux driver development, particularly for linux driver of the key technology, driven to the realization of a vital theoretical basis. Second, represent the hardware and the design of the device drivers on the basis of the overall of the system. Implementation the drivers of modules. Finally, design a tested software for system, and use effect figure to prove the validity and viability of the system designs and the performance of the modules.
