Design and Implementation of NAND Flash Driver in Digital TV

With the global development of digital broadcasting,digital television has become the mainstream of market,SOC processor chips integrated analog and digital TV source decoder and high capabilities of post-processing has broad market prospects.As a kind of large-capacity storage devices,NAND Flash meets the harsh requirements of power,size,cost and resistance to shock by embedded system,which has been widely used.This paper probes into the principles of the NAND Flash devices in DTV and the design and implementation of NAND Flash driver based on the framework of Linux.
