摘要
随着全球电视数字广播的发展,数字电视已然成为市场的主流,集成模拟和数字电视信源解码和高端后处理能力的SOC核心处理器芯片具有广阔的市场前景。NAND Flash作为一种大容量的存储设备,满足了数字电视嵌入式系统对功耗、体积、成本及抗震性的苛刻要求,因而得到了广泛的应用。该论文主要探讨NAND Flash设备在数字电视中的工作原理以及基于Linux系统框架下的NAND Flash驱动程序的设计与实现。
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.
